• Porsche 997 MK1 GT2 2007-09

Diagram Ref No 4

What This Product Does:

• These hoses/pipes are part of the charge-air system (after the turbocharger) and connect components like the turbo(s) → intercooler(s) → intake manifold(s). They carry compressed air at elevated pressure and temperature.
• The purpose: When the turbo compresses intake air, it gets hot; after the intercooler it is cooled, then routed via these hoses to the engine. Secure, leak-free hoses ensure the engine receives correct volume and pressure of air.
• If the hose is compromised (e.g., leak, crack, split), then boost pressure drops, the engine may lose power, run richer/leaner, trigger fault codes, and the car’s performance degrades.

Symptoms & Signs You Might Need Replacement:

• Loss of boost / reduced power: If you’re not getting full boost, or turbo seems slower to build, a leak in this hose is a common fault.
  
• Hissing or whistling noise during acceleration (especially under load) — indicates air escaping from pressure side of the system.
  
• Check Engine Light / fault codes relating to boost pressure, turbocharger performance or intake air pressure.
  
• Visible damage or wear: cracks, splits, swelling, hose soft spots, or hose clamps loose or missing.
  
• Oil or dirt buildup around the hose connection points — may suggest a leaking pressure hose has allowed contaminants in.
  
  

Why Replacement Matters:

• Restores correct performance: For a turbocharged 911, accurate boost pressure and charge-air delivery are critical for performance. A failing hose disrupts that.
  
• Prevents further damage: A leaking charge air hose can lead to incorrect air/fuel mixture, cause lean conditions, increase exhaust temps, or stress the turbo/intercooler system.
  
• Safety & drivability: A compromised hose might fail catastrophically under boost, leading to a sudden loss of power, which could be dangerous in certain driving conditions.

Diagram Ref No 5

What This Product Does:

• This water hose is part of the engine cooling system — it routes coolant between components of the cooling circuit (likely between the water pump / oil cooler / radiator or similar) doing a “3-way” path.
• It ensures coolant flows properly, helping regulate engine temperature, protect components from overheating, and maintain correct thermal management.
• Because modern Porsche engines operate with tight tolerances and high performance, correct hose routing, quality of hose material, and correct diameter are important to avoid flow restrictions, leaks or hose collapse.

Symptoms Of Wear / Damage / When To Replace:

• Visible cracking, bulging, swelling or hose softening at clamps or along the hose length — hose material degrades with heat, age and coolant exposure.
  
• Coolant leaks around the hose or hose clamps — signs of coolant around the hose, white or green crust, or low coolant level without obvious reason.
  
• Overheating or elevated engine temperatures — if a hose is degraded or collapsed, it can restrict flow and reduce cooling system efficiency.
  
• During engine work: If you’re already removing parts of the cooling system (water pump, oil cooler, hoses) and the hose looks old, it’s sensible to replace this unit to avoid future failure.
  
  

Why Replacement Matters:

• Ensuring coolant integrity and flow: A failing hose can compromise coolant flow and temperature regulation, potentially leading to serious engine damage.
  
• Prevents unexpected breakdowns: Considering the cost of engine damage, or expenses related to overheating, replacing aged hoses is cost-effective preventive maintenance.
  
• Supports longevity and reliability: Especially in performance vehicles like Boxster/Cayman, cooling system maintenance matters for engine life, performance consistency and resale value.
  
• Saves labour in the long term: Since many cooling hoses are hidden or routed behind other components, replacing while you have access prevents having to revisit the job later.

• Porsche 997 MK1 GT2 2007-09

Diagram Ref No 16

What This Product Does:

• The cable guide holder is a small but important bracket/guide piece that helps route, secure and align the shift-cable (or selector cable) linking the shift lever/console and the gearbox’s Tiptronic actuator.
• Proper alignment and secure routing of the shift cable is vital for smooth, accurate gear selections and the correct functioning of the Tiptronic automatic shift system. If the cable moves, binds or is mis-routed, the gearbox may fail to shift properly or may show incorrect positions.
• The guide ensures the cable sits correctly, doesn’t rub against other components, remains fixed in its correct path, and retains positional integrity over time.

Symptoms & Signs Of Wear / When To Replace:

• Unreliable gear selection or delay/shudder in Tiptronic shifts. If the shift cable is mis-routed or the guide broken, the shift linkage may not be precise.
  
• Loose cable mounting, excessive play or unusual noise coming from the gearbox shift area — indicating the guide might be cracked or missing.
  
• Visible damage, missing bracket, or parts out of place in the gearbox/shift cable area (often when inspecting the underside or shift linkage of the car).
  
• When performing gearbox service or replacing the shift-cable assembly: if the guide is worn, cracked or corroded it is often prudent to replace it to restore full linkage integrity.

Why Replacement Matters:

• Ensures accurate shifting: Even though it’s a small part, the cable guide contributes to precise gear shift linkage. A damaged or missing guide can degrade the driver’s experience and potentially the safety/operation of the gearbox.
  
• Prevents future wear: A mis-routed cable may rub or chafe on surrounding components leading to accelerated wear or eventual cable or bracket failure — replacing the guide avoids this.
  
• Cost-effective maintenance: If you’re already working on the tiptronic system (shifter, cable, valve body), replacing this guide is cheap and prevents the possibility of repeating jobs due to neglected small parts.

Radial Shaft Seal For Bush Version, 43.8MM X 62.1MM X 7.7MM.
Restore the integrity of your drive-train with this genuine radial shaft seal for Porsche Cayenne 955 series models. Designed to fit a shaft dimension of 43.8 mm ID × 62.1 mm OD × 7.7 mm thickness, this seal ensures reliable sealing of rotating shafts, prevents oil/grease leakage and blocks contamination ingress.

Fits:

• Porsche 955 Cayenne 3.2L V6 2003-06
• Porsche 955 Cayenne S 4.5L V8 2003-06
• Porsche 955 Cayenne Turbo 4.5L 2003-06
• Porsche 955 Cayenne Turbo S 4.5L 2006>>

Cars With Option Codes:
G0R - Tiptronic S

Diagram Ref No 5

What This Product Does:

• A radial shaft seal is used where a rotating shaft (such as a drive shaft, gearbox output, differential input, etc) passes through a housing. Its job is to maintain a tight seal between the shaft and housing to prevent fluid (oil, gear lube) leakage and prevent ingress of dirt, dust or moisture.
• In this particular application (Cayenne drive-train / transmission area) it ensures the correct lubrication stays in place around the rotating component and helps protect bearings and shafts from contamination.
• By maintaining correct sealing, it supports long-term drive-train integrity, reduces wear and prevents leakage that could lead to bigger mechanical failures.

Symptoms & Signs Of Wear / When To Replace:

• Fluid leaks around the shaft housing. For example oil or gear-oil visibly seeping / dripping from the area where the seal sits.
  
• Excessive play or noise in the drive-train or shaft area, which may indicate seal failure allowed contamination and led to bearing deterioration.
  
• Contamination or dirt ingress around the seal housing — if the seal lip has lost contact, dirt may be visible in the housing.
  
• Visible damage to the seal such as hardened rubber, cracked lip, missing spring, or nicks in the sealing surface.
  
• When servicing the shaft or housing area: if the seal is disturbing or old (many years/mi), replacing it while the unit is accessible is often prudent.

Why Replacement Matters:

• Prevents major fluid loss: A failed seal may allow lubrication to escape which can lead to shaft bearing failure or gearbox/differential damage — replacing it is much cheaper than replacing major components.
  
• Protects internal components: A good seal keeps dust and moisture out, preserving bearings, splines, shafts and preventing accelerated wear.
  
• Maintains performance and reliability: When seals are intact the drive-train operates quietly, smoothly and with less maintenance concern.
  
• Maintenance and peace of mind: Especially for a high-end vehicle like a Cayenne, ensuring all seals are in good order supports confidence in long-term use and resale value.

Micro Switch For Bonnet.
Restore the accurate “hood open/closed” signal function on your Porsche Cayenne with this genuine OEM micro-switch. Designed to detect the hood’s state and interface with the vehicle’s safety and alarm systems, this contact switch is located in the front hood latch assembly and ensures proper warning-light operation and secure bonnet closure.

Fits:

• Porsche 955 Cayenne 3.2L V6 2003-06
• Porsche 955 Cayenne S 4.5L V8 2003-06
• Porsche 955 Cayenne Turbo 4.5L 2003-06

• Porsche 957 Cayenne 3.6L 2007-10
• Porsche 957 Cayenne S/GTS 4.8L 2007-10
• Porsche 957 Cayenne Turbo / Turbo S 4.8L 2007-10

Diagram Ref No 22

What This Product Does:

• The switch is mounted in the hood latch area or hood hinge/lock assembly and serves to detect the position of the bonnet: closed or open. When the hood is closed properly, the switch is actuated (pressed) and sends a signal (to the vehicle’s body control module, instrument cluster, alarm system, etc).
• Its roles include enabling or disabling warning lights (e.g., “Hood open” indicator), interfacing with the alarm/immobiliser system (to detect unauthorised opening), or controlling internal functions like interior lighting, fusebox cover, etc.
• A correctly functioning micro-switch ensures that the vehicle knows the hood’s state, enabling proper safety, alarm and signalling behaviour.

Symptoms Of Wear Or Failure:

• The instrument cluster shows a persistent “Hood open” warning when the bonnet is actually closed (false open indication).
• The hood needs to be slammed or adjusted so that it stops the warning light — meaning the switch may not be actuating correctly when the bonnet is closed.
• Alarm/door-lock systems behave incorrectly or trigger incorrectly due to hood-open signal malfunction (for example, alarm triggering when hood is closed).
• Physical damage to the switch: broken housing, corroded contacts, bent actuator plunger, or the part is worn, intermittent or stuck.
• During bonnet latch replacement, hinge repair or following an accident, the switch may have been damaged, mis-aligned or disconnected.

Why Replacement Matters:

• Safety & functionality: Because the hood-open signal is linked to vehicle safety systems (alarm, immobiliser, interior lights), a faulty switch can lead to wrong warnings, false alarms or safety system issues.
  
• Proper alarm/immobiliser operation: A working bonnet switch helps the vehicle detect unauthorised access under the hood — essential for security.
  
• Accurate indication: You want the “hood closed/open” indication to be correct — if not, you may drive with the bonnet not properly secured or you may ignore warnings thinking they’re false.

• Porsche 997 MK1 Carrera 4 3.6L 2005-08
• Porsche 997 MK1 Carrera 4S 3.8L 2005-08

Diagram Ref No 30

What This Product Does:

• The breather hose is part of the engine’s ventilation or crankcase/air-oil management system. In this case, it's described as being located at the top of the oil-cooler, which may mean it connects the crankcase ventilation or engine breather output back into the intake or another system.
• Its main function: to provide a path for gases (blow-by, vapor, pressure) from the engine or oil-cooler area back into the intake system or safe discharge path.
• The hose must withstand engine heat, pressure/vacuum cycles, vibrations, and exposure to oil or vapour, and provide a leak-free connection.
• Proper functioning helps maintain correct crankcase pressure, prevents undue pressure build-up or vacuum, helps control emissions, keeps the oil cooler circuit operating correctly, and ensures the engine’s ventilation system does not allow unintended air or oil vapour to escape or enter in the wrong way.

Symptoms Of Wear Or Failure:

• Oil vapour or smell around the engine compartment, especially near the oil cooler area or hose routing, indicating leakage of crankcase gases.
  
• Visible cracks, splits, brittleness, or hose collapse — old hoses can harden, crack or collapse internally causing blockage or leakage.
  
• Unusual engine behaviour: e.g., increased oil consumption, engine smoking slightly, or unusual intake/vacuum behaviour — if ventilation is compromised.
  
• Check engine or emission warnings: A compromised breather hose may lead to induction of unmetered air or vapours, affecting engine management.
  
• Oil cooler area contamination: Because the hose is described as located at the top of the oil cooler, if oil or vapour-contaminated deposits are visible there, the hose may be failing.
  
  

Why Replacement Matters:

• Maintains correct engine ventilation: A good breather hose ensures proper crankcase/ventilation flow, and prevents pressure build-up or vacuum conditions that can lead to leaks or part failures (seals, gaskets).
  
• Protects the oil-cooler circuit and engine components: Because this hose is located at the oil-cooler top, replacing it helps ensure the oil cooler and associated hoses remain uncontaminated by vapour or oil mist escaping via degraded hoses.
  
• Improves reliability: Since these hoses are subject to heat, pressure and ageing, replacing them proactively avoids sudden failure, which could leave the car stranded or cause engine issues.

Diagram Ref No 8

What This Product Does:

• The actuator button/lever is the user-interface element on the seat that allows you to release and fold the rear portion of the seat back (or fold the seat backrest forward) so you can access the rear compartment or improve cargo access.
• When you press or actuate it, it triggers the internal latch mechanism in the seat backrest — allowing the backrest to pivot or fold.
• Because it’s styled in Galvano Silver, it also contributes to the interior finish of the seat side panel/trim, so it’s both functional and cosmetic.
  
• A proper ergonomic and tactile button means the folding backrest function works smoothly, the lever retains feel & finish, and the seat looks as the manufacturer intended.

Symptoms & Signs of Wear / When To Replace:

• The folding backrest function is hard to engage or the lever feels sloppy, wobbly or loose — indicating the mechanism or mounting is worn.
  
• The finish or surface of the button is scratched, faded, or damaged (especially with the Galvano Silver finish) and the interior aesthetic is compromised.
  
• The button/lever is missing or cracked, or the surrounding trim is broken — compromising both function and appearance.
  
• The backrest mechanism doesn’t release properly — sometimes the button might actuate but the latch doesn’t respond because the lever or pivot is worn.

Why Replacement Matters:

• Functionality: The folding backrest feature is convenient for access or for increased cargo flexibility. A faulty button/lever can degrade that convenience.
  
• Quality and Finish: For premium vehicles like the Porsche 911/Cayman, every interior detail matters. Having the correct Galvano Silver finish lever maintains the high-quality look and value.
  
• Prevents bigger issues: If the lever is worn or loose, it may accelerate wear on the latch mechanism, the fold hinge, or cause misalignment of the seat back which may lead to squeaks, rattles or safety issues.

288 - Headlamp Washer

Diagram Ref No 5

What This Product Does:

• The washer hose connector links the washer fluid hose to either the headlight washer nozzle (pop-up or non-pop-up) or to the supply line, ensuring the washer fluid is delivered to the headlight washer jets.
• It must maintain a secure, leak-free connection under vibration, thermal cycling and pressure when the washer system is activated.
• Ensures that when you trigger the headlight washers (e.g., press the button or activate with wipers), the fluid flows correctly to clean the headlight lens as intended.

Symptoms Of Wear Or Failure:

• Washer fluid leaking around the headlight washer nozzle or downstream of it — often a sign the connector is damaged or the hose isn’t secured properly.
  
• Headlight washer jets not functioning, or fluid not reaching the headlight nozzles despite the pump activating. This may indicate a broken or disconnected connector.
  
• Hose detachment: a hose might have pulled out of the connector, or the clip/insert may be damaged, causing the hose to pop off under pressure.
  
• Visible damage or corrosion: the connector or its mounting might show cracks, deformation, corrosion or missing clip.
  
• Reduced headlight washer performance: e.g., weak spray, intermittent spray, or only one side works — could be the connector on the non-working side.
  
  

Why Replacement Matters:

• Restoring full functionality: If the headlight washer system fails, headlight lenses may get dirty (especially in winter/snow/salt conditions) reducing visibility and compromising safety.
• Preventing further leakage: A failed connector may lead to fluid leaks which can drop onto tyres or bodywork, or lead to corrosion of nearby components.
• Ensuring correct fit & finish: Using the correct Porsche-specified connector ensures the hose and nozzle interface is correct and the system remains reliable.

Symptoms & Signs You Might Need Replacement:

• Visible damage or missing liner inside the front wheel arch: e.g., split or cracked plastic, detachment, missing fasteners, or the liner entirely absent.
  
• Excessive dirt, debris or corrosion inside the wheel arch or on inner body panels — if the liner is compromised, the arch is less protected.
  
• Unusual wheel-arch noise or increased road noise: If the liner is loose or missing, suspension components may be exposed and road spray or debris may enter areas that were previously shielded.
• Wear from age: These liners may become brittle, cracked or partially detached with age, particularly on cars used in regions with road salt or heavy use.
  
  

Why Replacement Matters:

• Component protection: Replacing a damaged liner protects suspension, brake lines, wiring and body panels from damage and corrosion.
  
• Vehicle integrity and value: For premium or collector cars like the 911, original-fit liners help maintain appearance, fitment completeness and resale value.
  
• Finish and appearance: Ensures that the wheel arch area looks correct, aligns with bodywork, and the interior of the arch isn’t exposed.
  
• Noise/Vibration: Proper liners help reduce ingress of road spray, minimise wheel-well noise and contribute to a refined driving experience.
  
• Preventative maintenance: Installing a new liner before serious damage occurs is cheaper than dealing with rust, debris-damage or incorrect suspension component exposure later.

Diagram Ref No 3

What This Product Does:

• The centre undertray (or belly pan) is a large panel mounted underneath the vehicle, typically in the under-body centre section. Its functions include:
• Noise/Vibration/Harshness) reduction: by covering the underbody it helps reduce road noise and wind noise in the cabin.
  
• Aerodynamic improvement and underbody protection: providing a smoother underside, it helps reduce drag and aids airflow beneath the vehicle.
  
• Protection of vital components: the undertray shields components on the underside from road debris, water spray, and minor impacts (curbs, debris) that might otherwise damage suspension, exhaust, plumbing.
  
• In effect, it is a functional body-panel that sits beneath the car’s mid/centre section, helping the car perform better, stay quieter and better protected.

Symptoms & Signs You May Need Replacement:

• Visible damage, cracks, missing sections or broken fasteners — due to scuffs against curbs, underbody impacts, or age-related degradation.
  
• Underbody noise increase or vibration — if the undertray is loose, missing or damaged the underbody acoustic performance may suffer.
  
• Increased drag or wind noise — if the panel is warped or detached in spots, you may notice more wind howl or lowered top-speed performance (especially in performance cars).
  
• Exposure of components — if you see components normally covered (e.g., plumbing, wiring, underside of the engine/transmission) then the undertray may be missing or removed.
  
  

Why Replacement Matters:

• Improves drivability & comfort: A sound underbody panel improves the feel inside the cabin, reducing wind/road noise and helping the car feel more refined.
  
• Maintains aerodynamic efficiency: Especially on high-performance Porsche models, having the underbody panel in place helps maintain the designed airflow and downforce characteristics.
  
• Protects underbody equipment: Without the undertray you risk stone strikes, water spray and debris hitting vulnerable components (fuel lines, oil lines, exhaust) directly.
  
• Avoids costly damage: A thrown stone or curb contact could damage a part that otherwise the undertray shielded; replacing soon means fewer downstream issues.

Diagram Ref No 9

What This Product Does:

• As a high-pressure / pressure line, it carries refrigerant under high pressure from the A/C compressor to the condenser or from the condenser onward in the refrigeration cycle.
• It must withstand elevated pressures (hundreds of psi depending on system), high temperatures, thermal cycling, vibration, and hold a leak-tight seal under service conditions.
• A correct pressure line ensures the A/C system maintains proper pressures (both high side and low side), operates efficiently, delivers cold air and prevents refrigerant loss.
• If this line is compromised (leak, collapse, corrosion) the A/C system may lose refrigerant, pressure drop, reduced cooling or fail to function.

Symptoms Of Wear, Damage Or Need For Replacement:

• A/C cooling performance drops sharply — e.g., the system does not achieve low cabin temperatures, or takes much longer than expected. A leak in the high-pressure side is a common culprit.
  
• Visible damage to the line — cracks, corrosion, brittleness, fractured fittings, or evidence of oil or refrigerant residue around the pipe or its fittings (oil stain often indicates refrigerant leak).
  
• Hiss or bubbling noise near the A/C piping/hoses, particularly after the compressor runs, as refrigerant escapes.
  
• Low refrigerant charge or repeated recharging required — if you find the system needs frequent top-ups, the pressure line might be leaking.
  
• On inspection — The hose or rigid pipe section is degraded, the O-rings at the fittings are worn, or the mounting clips/brackets are missing, causing undue movement/vibration.

Why Replacement Matters:

• System efficiency & comfort: A faulty high-pressure line compromises the A/C system, reducing cooling comfort, increasing cabin temperature and putting strain on the compressor.
  
• Preventing further damage: Leaks in this line allow ingress or egress of refrigerant and lubricant, risking damage to the compressor, condenser, drier, or causing contamination. Replacing a damaged line is much cheaper than replacing major A/C components.
  
• Maintains system integrity: Using the correct Porsche-specified line ensures correct fit, correct diameter, correct pressure rating and correct routing — generic hoses may not meet the high-pressure or corrosion-resistance requirements.
  
• Safety & environmental responsibility: Refrigerants are under high pressure and treatment of leaks is a regulatory / environmental issue; ensuring the line is sound prevents uncontrolled release.

RIGHT Interior Door Mirror Trim RHD, Electrically Adjustable, Black Grey.
Restore the appearance and integrity of the door-mirror assembly on your right-hand drive Porsche with this genuine OEM trim cover. Designed for the electrically adjustable door mirrors, this cover fits on the right side and completes the assembly by covering mirror mount components and wiring, while matching factory finish and alignment.

Fits:

• Porsche Boxster 986 2.5L 1997-99

Cars With Option Codes:
012 - "Sport Design" Package
016 - "Standard" Package

Diagram Ref No 12

What This Product Does:

• This mirror cover trim functions as the external finishing piece on the door mirror assembly: it fits around the mirror base or where the mirror connects to the door, covering the internal mounting points, wiring harness, adjustment motor housing, and provides a seamless external appearance.
  
• Because the mirror is electrically adjustable, this cover helps protect the delicate mirror motor/wiring assembly from water ingress, debris, vibration and ensures the wiring routing remains hidden and clean.
• It also helps retain aerodynamic and stylistic integrity: the correct trim ensures the mirror assembly looks as the manufacturer intended, aligning flush with the door panel, matching paint or trim finish and preventing wind-noise or water leaks at the mirror mount.

Signs You Might Need Replacement:

• The mirror cover trim is cracked, damaged or broken, which may expose wiring or internal mirror mount components.
  
• The cover is missing entirely, or was removed and not replaced during a mirror repair or door panel replacement.
  
• The exterior appearance looks unfinished, misaligned or the mirror base contains visible mounting hardware — indicating the trim cover is absent or incorrectly fitted.
  
• You’re restoring the vehicle to high appearance standards and want the correct OEM cover replacing an old/preserved piece that has aged, faded, scratched or lost its fit.

Why Replacement Matters:

• Appearance & finish: As a visible part of the door mirror assembly, the trim cover impacts the overall exterior look of the vehicle. A proper fit and finish is important for premium vehicles like the relevant Porsche models.
  
• Protection & durability: The cover helps shield the mirror motor, wiring and mounts from the elements (rain, debris, vibration). Without a proper cover, wires may be exposed, and water ingress could lead to mirror motor failure or corrosion.
  
• Restoration/value maintenance: For a high-value vehicle, having correct OEM exterior trims (mirror cover, painted or unpainted) contributes to authenticity, build quality and resale value.
  
• Completes mirror assembly: When replacing the mirror or servicing the door panel, the cover is often overlooked; replacing it ensures the job is truly finished and the mirror assembly returns to factory specification.

Designed for 1998-2005 911 (996) models (including Carrera, Turbo variants) these hoses ensure your engine’s breather or cooling-vent line operates correctly—preventing vapour or pressure buildup, supporting correct engine ventilation and maintaining system reliability.

Fits:

• Porsche 996 C2 3.4L 1997-08/01
• Porsche 996 C4 3.4L 1997-08/01
• Porsche 996 C2 3.6L 09/01-2005
• Porsche 996 C4 3.6L 09/01-2005
• Porsche 996 C4S 3.6L 09/01-2005
• Porsche 996 TURBO 2000-05

Diagram Ref No 21 And 22

What This Product Does:

• In the context of the engine / cooling / ventilation system, a “breather line” or “vent hose / vent line” allows controlled venting of crankcase or cooling system gases, or supports the cooling/overflow/expansion system to relieve pressure, direct vapour, or provide required venting.
• These hoses ensure air or vapour that builds up is not trapped in the engine/cooling system, allow system pressure to stabilise, and maintain correct service behaviour of the engine’s ventilation or cooling circuits.
• They also help prevent buildup of pressure/vapour that could otherwise lead to malfunction, leaks or driveability issues.

Symptoms Of Wear, Damage Or When To Replace:

• Hose visible damage, cracking, brittleness or detachment — Over time, heat and age degrade rubber/hose materials.
  
• Engine or cooling system venting issues — for example, if you smell vapour/odour, see coolant or oil vapour escaping in unusual places, or lid caps popping off unexpectedly.
  
• Unusual noise or hissing from the engine bay or venting hose areas—possibly indicating a leak or damaged hose.
  
• Performance degradation in the ventilation/cooling system—such as elevated temperatures, pressure spikes in cooling, or increased oil consumption if the hose is a crankcase breather.
  
• Poor condition hoses in older vehicles—since these parts are often overlooked in maintenance, especially with older 996 models, they may be degraded and benefit from preventive replacement.
  
  

Why Replacement Matters:

• Maintains correct system function: A properly functioning breather line ensures your engine’s ventilation/cooling systems are working as intended — preventing pressure buildup, vapour trapping or system inefficiencies.
• Prevents secondary damage: A failing hose might lead to undue pressure or vapour escaping in unwanted places, which can damage hoses, connectors, engine seals or other vulnerable parts.
• Helps reliability and longevity: Especially in older 996 models, replacing old, brittle, cracked hoses with fresh OEM-spec units avoids failures that can strand the vehicle or lead to more expensive repair.
• Peace of mind & maintenance value: Ensuring the ventilation path is intact supports the overall health of the engine and cooling system, which can matter for resale or restoration quality.

Water Hose.
Renew the coolant overflow connection on your Porsche Boxster with this genuine OEM overflow hose. Designed for the Boxster 1997-2008, this main fill/overflow hose links the cooling system to the expansion reservoir, ensuring proper coolant expansion, return flow and system pressure stability.

Fits:

• Porsche Boxster 986 2.5L 1997-99
• Porsche Boxster 986 2.7L 1999-02
• Porsche Boxster S 986 3.2L 1999-02
• Porsche Boxster 986 2.7L 2003-04
• Porsche Boxster S 986 3.2L 2003-04
• Porsche Boxster 987 2.7L 2005 -08/08
• Porsche Boxster 987 S 3.2/3.4L 2005-08/08

Diagram Ref No 29

What This Product Does:

• This hose functions as the connection between the cooling system (likely radiator or coolant header) and the overflow/expansion reservoir. When coolant expands under heat or pressure, surplus fluid flows into the reservoir; conversely when the system cools, fluid returns.
• Ensures that cooling system overflow is safely directed, that the reservoir receives the fluid, and that the cooling circuit maintains correct pressure, volume and recirculation.
• Proper operation helps avoid coolant loss, maintain correct cooling system levels, and helps prevent boil-over or overheating due to un-controlled coolant expansion.

Symptoms Of Wear Or When To Replace:

• Coolant leakage around the reservoir, hose clamps, or along the path of the overflow hose — e.g., dripping coolant, crusty residue near joints.
  
• Overheating or low coolant, where the expansion reservoir remains dry, suggesting the hose isn’t delivering returning fluid or has collapsed.
  
• Burst, cracked or hardened hose— rubber hoses degrade with heat/age, causing soft spots, bulges, cracks or collapse under pressure.
  
• Hose slack or loose clamps— if the hose is long out of service it might sag, the ends may be brittle, or clamps may be corroded leading to poor seal.
  
• If the vehicle is running very hot or the coolant level drops unexpectedly, and checks show the overflow system not functioning properly.
• On older Boxsters many cooling-system hoses are aged and replacement is preventive maintenance.

Why Replacement Matters:

• Maintains cooling system integrity: A faulty overflow hose can lead to coolant loss, pressure escape or improper reservoir return—affecting system performance and engine cooling.
• Prevents overheating or coolant loss: Since the hose handles expansion flows, failure can result in overflow at wrong points or low reservoir levels, which may lead to engine overheating or damage.
• Reliability and longevity: Rubber coolant hoses degrade over time due to heat, vibration and pressure cycles — replacing them restores system reliability.

• Porsche 993 (911) TURBO S 1994-97

Diagram Ref No 2

What This Product Does:

• This lock cylinder assembly sits behind the external door handle and is the mechanism which allows the door to be locked or unlocked via key from the outside.
• The keyed lock cylinder ensures security (locks the door), and the “coded” aspect ensures compatibility with the vehicle key system (which can include central locking or key-matched sets).
• Correct fitment ensures the door handle and lock engage properly, the key insertion is correct, the internal mechanism aligns and the lock both secures the door and allows smooth access.

Symptoms Of Wear Or When You Should Replace It:

• Key won’t turn, sticks or is difficult to insert—in the door handle lock area. This suggests the cylinder may be worn, corroded or jammed.
  
• Door won’t lock or unlock via the key from outside, or the key simply spins freely indicating internal cam/shear failure.
  
• Mismatched key numbers: if the door lock is not operating with your existing key, or you have two different keys for left/right doors and want to unify them.
  
• Corrosion or damage: the lock barrel may show signs of rust, binding, broken mounting tabs or wear of the key slot—common after many years of service.
  
• After bodywork or door replacement: If the door or handle assembly has been replaced or re-painted, the lock cylinder might be damaged or mismatched—installing a correct coded cylinder ensures proper fit.
  
• When restoring the vehicle or upgrading security: a key-matched cylinder ensures your doors work with the master key and reduces the number of keys.

Why Replacement Matters:

• Security: A worn or malfunctioning lock cylinder compromises door security—important for a performance car like the 993.
  
• Convenience: Ensures your existing key operates both sides (or the correct side) without needing multiple keys, re-keying or workaround.
  
• Fit & finish: OEM cylinders ensure correct handle fitment, proper alignment, correct key engagement, and preserve vehicle authenticity.
  
• Reliability: Avoids the situation where a worn cylinder fails entirely — meaning you cannot lock/unlock the door with the key from outside, which could be inconvenient especially if central locking is involved.
  
• Resale & value: For a classic like the 993, correct functioning door locks with key-matched cylinders contribute to overall restoration quality and value.

Diagram Ref No 9

What This Product Does:

• When you pull the release handle inside the car (or via the remote release), this cable is under tension and the movement pulls the latch lever on the rear lid, allowing the lid to open.
• The “guide tube” part provides support for the cable, keeps it aligned, prevents kinks or chafing, and helps maintain smooth operation.
• Without this cable functioning properly, the rear lid may not open (or may open unpredictably), causing inconvenience or failure to gain access to the engine bay/trunk area.

Symptoms Of Wear Or Failure:

• The lid release inside the cabin doesn’t operate the rear lid — i.e., you pull the handle and the lid doesn’t release.
  
• Sticky, stiff or jerky release operation — the cable may be sticking in the guide tube, stretched or frayed.
  
• Visible damage to the cable or guide tube — corrosion, frayed wire, broken sheath, kinks in the tube.
  
• Rear lid latch mis-behaviour — the lid may pop open unexpectedly, not latch properly, or you may need to repeatedly pull the handle.
  
• When restoring a vehicle or replacing rear lid components (hinges, latch, seal) the cable is often overlooked but can be worn due to age (especially in 964/993 cars).

Why Replacement Matters:

• Ensuring reliable access: The rear lid is your access point for the engine bay/trunk; a non-resilient or broken cable means you might be unable to open the lid when needed.
• Safety & utility: If the lid cannot latch properly or stays partially unlocked, this could cause it to fly open while driving or not secure properly.
• Prevents further damage: A worn cable can cause excessive load on the latch, hinge or release handle mechanism, accelerating wear or causing mis-alignment.
