About Kits

Kits for Porsche

Design911 offers an extensive selection of package deals for Porsche parts, providing an ideal solution for Porsche enthusiasts looking to upgrade, maintain, or personalise their vehicles. These packages are thoughtfully curated to include complementary components, helping with compatibility and overall cost-effectiveness

A Quick Look at Kits

Kits information on this page is based on details supplied by the manufacturer or distributor, plus any OE references provided with the parts.

Choosing the Right Fit for Your Porsche

Where Kits are listed for Porsche, use the supplied model coverage and OE references to confirm suitability. Check details that commonly affect fitment such as model year, axle or side, and any option codes or connector types where relevant.

  • Typical reasons people choose kits include wanting all the right Porsche parts in one order, reducing the risk of missing seals, clips, or one-time-use fixings, and saving workshop time.
  • Kits help ensure matched components (for example, brake refresh kits, service kits, or suspension refresh kits) so parts work together as intended.
  • Common real-world triggers include repeated failures because a small supporting part was not replaced, mixed part revisions, or mismatched specification between components.
  • If problems occur, they are often traced to incorrect vehicle selection, old core components not addressed, or installation shortcuts rather than the kit itself.
  • Before you start work, compare the kit contents with the Porsche PET diagram and your job list so you know exactly what is included and what may still be needed.
  • Always confirm whether kits are vehicle-specific, and check if bolts, clips, fluids, and other one-time-use hardware are included or need to be added separately.

Browse by Category

If you already know the area you are working on, start with the category and then filter by Porsche model. Where real-world symptoms and typical reasons to replace are provided, use them to keep the wording grounded.

Brakes — Brake components are renewed to restore stopping performance, address wear or upgrade a Porsche for fast road or track use. Common symptoms include vibration under braking, increased stopping distances, squealing, pulling to one side, warning lights and visible wear to discs and pads.

  • Check whether new fitting kits and wear sensors are included or should be added separately.
  • Confirm if parts are OE-equivalent replacements or higher-friction performance upgrades before ordering.

Brake Pads Packages — Brake pad packages group matched front and rear sets, making it easier to renew all pads at once for consistent feel and balance across the axle. Worn pads can cause squealing, low pedal feel, longer stopping distances and may score discs if run down to the backing plates.

  • Verify whether the package covers front, rear, or both axles and whether it is a standard or performance compound.
  • Check the contents list for anti-squeal shims, hardware and any wear sensors you may want to replace at the same time.

Gearbox / Transmission — You change gearbox and transmission parts when you have shifting issues, noise, leaks, or you are refreshing a high-mileage drivetrain. It is also common during clutch upgrades or ratio changes. Typical symptoms include whining in a specific gear, crunching on shifts, or difficulty selecting gears, as well as leaks at seals or casing joints.

  • Not all noise or poor shifting means the gearbox itself is failing—mounts, linkage, clutch, and oil condition can produce similar symptoms.
  • Using the correct-spec gearbox oil and refreshing it is often a sensible first step before major work.

Service Parts — Service parts are replaced as routine maintenance to keep the engine and systems reliable, efficient, and protected. Doing this on schedule reduces wear, helps prevent breakdowns, and maintains performance—especially on older Porsche models where neglected servicing can quickly lead to costly repairs. Symptoms prompting attention include hard starting, rough idle, reduced fuel economy and poor throttle response.

  • Both OEM and reputable aftermarket parts can be suitable—always match the correct specification for your Porsche.
  • Keeping a clear service log helps diagnostics later and can support the car’s resale value.

Service Kits — Service kits bundle the correct parts for a routine Porsche service into one package, reducing ordering mistakes and ensuring you can reset the car to a known maintenance baseline. They are ideal when catching up on overdue work or planning regular servicing to a consistent standard. Symptoms leading to a full kit are often general, such as sluggish running, inconsistent idle, poor economy, or increased engine noise from old oil and filters.

  • Service kits typically include filters and key consumables, but contents vary—check the list carefully and add any extra items you want to replace while access is good.
  • Kits are usually specific to model, year and engine, so confirm these details before ordering.

WIPERARMKIT911.RHD
Product Information
Product Information
Wiper arms, blades & fitting kit including cap. RHD Cars Front. 
includes 2x wiper arms, blades and fitting that fit over wiper shaft and under wiper arm.

Fits:
Porsche 911 1965 - 1989
Porsche 914 1970 - 1976

Diagram ref no 3, 4, 6, 7, 8, 9, 10, 11, 12, 27

This is a complete front windscreen wiper system kit designed specifically for right-hand drive (RHD) Porsche 911, 930 Turbo and 914 models. It combines OE Match replacement components with genuine Porsche-spec hardware and caps to deliver a full-service solution for replacing worn or missing wiper arms and blades, plus all the proper fittings required for secure installation.

The wiper arms transmit the motion from the wiper motor linkage to the blades, ensuring a consistent and effective sweep across the windscreen. The wiper blades themselves clear rain, mist and road spray to improve visibility, especially during wet weather. Proper mounting hardware secures these arms to the wiper pivot shafts, and protective caps guard the fasteners from corrosion while completing a clean, original-style finish. Using correct parts helps maintain proper blade contact and sweep pattern for optimal performance.

Wiper systems endure continuous stress from weather exposure, mechanical wear and corrosion - especially on older or classic cars. Worn arms can lose tension, causing poor blade contact; corroded hardware can seize or strip; and missing end caps expose fasteners to the elements. These issues reduce wiping effectiveness and compromise visibility in wet conditions, which can negatively impact driving safety. Replacing these components with OE Match and genuine Porsche parts restores the correct wiper sweep, protects critical fixings, and ensures a finished result that respects the original design intent.

Replace the front wiper arms, blades and fittings if:
•  Blades streak or chatter across the windscreen
  Wiper arms feel loose or misaligned
  Mounting hardware shows rust, wear, or damage
  Protective end caps are cracked or missing
  You’re performing a full windscreen wiper system refresh

Porsche 911 1965 - 1989
Porsche 914 1970 - 1976

Diagram ref no 4, 5, 6, 7, 8, 9, 10, 11, 12, 27

This is a comprehensive front wiper system kit for left-hand drive (LHD) Porsche 911, 930 and 914 models. It combines OE Match-quality and genuine Porsche components to replace the front wiper arms, blades, and all necessary mounting hardware including protective end caps and fitting parts.

Your vehicle’s front windshield wiper system relies on strong, accurately mounted arms and effective blades to maintain clear visibility in rain, snow, and wet conditions. This kit replaces worn or corroded components with OE-matched parts to ensure a true, even sweep across the glass, reducing streaking, chatter, and uneven pressure. Properly fitted wipers are essential for safety and driver confidence - especially at speed or in poor weather.

Over time, wiper arms and blades can corrode, weaken, or lose spring tension, and fixing hardware can become stripped or seized. This leads to poor blade contact, streaking, juddering, and reduced visibility in wet weather - which can be a safety hazard. Replacing the full front wiper assembly with this OE-matched kit restores reliable wipe performance and ensures your car is both safe and visually correct, crucial for driving confidence and show-quality restoration.

Replace your wiper arms, blades, and associated hardware if you notice:
  Streaking or skipping blades on the windscreen
  Loose or wobbly wiper arms
  Blades that don’t sit flat across the glass
  Corroded or damaged mounting hardware
  Missing or cracked wiper arm end caps

Product Information
Air / Oil Separator and hose kit.
This Air/Oil Separator Kit is a direct-fit engine crankcase ventilation service set for V8 Porsche models. It includes an OE Match Air/Oil Separator  plus two high-quality OE Match crankcase breather hoses - engineered to replace factory-aged components that can degrade from heat, oil vapor exposure, and age.

Fits:
Porsche 958 Cayenne S 4.8L 2011 - 2018
 * engine code: 4802

Porsche 970 Panamera S / GTS 4.8L 2010 - 2013
 * engine codes: 4820,4840

Porsche 970 Panamera GTS 4.8L 2014 - 2016
 * engine codes: CXPA,CXRA, CXR

Diagram ref no 1, 5 and 6

The kit comprises critical crankcase ventilation parts used in high-performance Porsche engines to separate oil from air in the crankcase breather circuit and return clean air back into the intake system. The air/oil separator captures oil mist and blow-by gases that form in the crankcase, preventing oil from entering the intake while ensuring the engine breathes correctly under load. The breather hoses are OE Match-engineered flexible tubes that connect the separator to the crankcase and intake ports, maintaining correct airflow paths and preventing vacuum leaks.

This complete kit allows for a professional service of the crankcase ventilation system in one go, ensuring proper sealing and restored functionality.

The air/oil separator collects and filters blow-by vapours that form during combustion, separating oil droplets from the air and returning them to the crankcase. This prevents oil consumption, reduces smoky exhaust and keeps the intake tract clean. It also regulates crankcase pressure so that seals, gaskets and piston rings remain protected.

The crankcase breather hoses maintain the pathways between engine crankcase ports and the separator, ensuring smooth, controlled airflow and preventing oil-laden air from contaminating intake components. Without functioning hoses, vacuum leaks and crankcase pressure imbalances can occur, leading to poor engine performance and increased oil spray inside the engine compartment.

Over time, the air/oil separator and breather hoses can clog with oil residue, harden, crack, or lose their ability to properly separate oil from air — especially on high-mileage engines or vehicles subjected to frequent high RPM use.

Failure of these components can lead to:
• Increased oil consumption and smoky exhaust
  Contamination of the intake and turbocharger with oil mist
  Erratic crankcase pressure, leading to gasket leaks
  Poor idle quality or check engine codes related to crankcase pressure

Replacing them with this OE Match kit helps restore correct crankcase ventilation system performance, protects your engine internals and maintains smooth engine operation.

Replace the air/oil separator kit if you notice any of the following:
  Visible oil residue around the separator or hoses
  Excessive oil consumption
  Smoke or oil smell from the tailpipe
  Engine runs poorly at idle or under load
  Fault codes pointing to crankcase pressure issues
  Hose cracks, split rubber, or visibly brittle components

Air conditioning (Air Con) evaporator blower motor and pollen filter set
incl. Expansion valve and o-ring seals.
This complete air conditioning (A/C) service kit is a comprehensive set of HVAC parts engineered to refresh or restore the climate control system on your Porsche 993. It combines key components - the OE Match evaporator core, A/C blower motors, pollen (cabin) filter, expansion valve, and essential O-ring seals - giving you everything needed for professional-grade A/C performance and leak-free refrigerant flow.

Fits:
Porsche 993 1994 - 1998

Diagram Ref No 5, 7, 34, 35, 37 and 38.

This set brings together core HVAC elements required for an efficient and reliable air conditioning system. At the centre is the OE Match A/C evaporator , the heat-exchange core that cools incoming air by removing heat from the refrigerant before it enters the cabin. Complementing it are two OE Match A/C blower motors that push air through the system, and a high-quality pollen filter that traps dust, pollen, and other airborne particles for cleaner cabin air.

The kit also includes the A/C expansion valve - a critical refrigerant metering device - along with appropriate O-ring seals to ensure tight, leak-free connections throughout the refrigerant circuit.

Kit Includes:
• OE Match A/C Evaporator – OE ref no 96457390100
• OE Match A/C Blower Motors –  OE ref no  96457201501 and  96457201601
• OE Match Pollen (Cabin) Filters –  OE ref no  96457201601
• OE Match A/C Expansion Valve –  OE ref no  92857312305
• O-Ring Seals –  OE ref no  99970743441 and  99970725141

Function

The A/C evaporator (96457390100) cools cabin airflow by absorbing heat from the incoming air via refrigerant circulation, delivering cold, comfortable air inside the vehicle.

The blower motors (96457201501 & 96457201601) generate and control airflow through the ducts and across the evaporator, ensuring you feel cool air at the vents when the A/C system is on.

The pollen (cabin) filter (99357247900) helps clean the air drawn into the cabin by removing contaminants and allergens, improving air quality and passenger comfort.

The expansion valve (92857312305) precisely meters refrigerant entering the evaporator, controlling pressure and cooling efficiency. Without proper metering, the A/C system can under-cool or freeze up.

The O-ring seals (99970743441 & 99970725141) ensure all refrigerant joints are sealed tightly, preventing loss of refrigerant and maintaining system pressure for effective cooling.

Air conditioning components degrade over time due to heat cycling, moisture exposure, and refrigerant pressure changes. A worn or failing evaporator can leak refrigerant or lose cooling capacity. Existing blower motors may weaken or fail completely, reducing airflow and cabin comfort. A clogged pollen filter restricts airflow and can circulate dust and allergens inside the cabin. Faulty expansion valves cause inefficient cooling or frost build-up, while old or hardened O-rings lead to refrigerant leaks, hurting system pressure and cooling performance.

Replacing these with quality OE Match parts and genuine seals ensures correct fit and restores the cooling system to its intended performance - keeping your cabin cool, comfortable, and leak-free all season long.

Recommend replacement if you observe:
•  A/C blowing warm air or weak airflow
•  Reduced or inconsistent cooling performance
•  Unusual blower noise or motor failure
•  Noticeable dust or odours from vents
•  Moisture or leaks in evaporator area
•  Difficulty maintaining A/C set temperature
•  As part of a full A/C system service

Air conditioning (Air Con) evaporator and blower motor set
incl. Expansion valve and o-ring seals.
This comprehensive air conditioning (A/C) system service kit bundles key HVAC components required to restore or upgrade the A/C performance in classic Porsche 911 (964 / 993) models. It includes the OE Match evaporator core, blower motors, expansion valve, and genuine O-ring seals necessary for correct installation and leak-free refrigerant performance.

Fits:
Porsche 964 1989 - 1994
Porsche 993 1994 - 1998

Diagram Ref No 5, 34, 35, 37 and 38.

This A/C service set is a combination of essential climate control components engineered to ensure your Porsche’s air conditioning system delivers reliable, cold airflow and maintains proper refrigerant flow throughout the system. The kit is ideal for A/C system rebuilds, evaporator replacement jobs, or when multiple HVAC components show wear due to age, moisture exposure, or refrigerant system fatigue.

Kit Includes:
• OE Match A/C Evaporator – OE ref no 96457390100
• OE Match A/C Blower Motor –  OE ref no  96457201501
• OE Match A/C Blower Motor –  OE ref no  96457201601
• OE Match A/C Expansion Valve –  OE ref no  92857312305
• O-Ring Seals –  OE ref no  99970743441 and  99970725141

This kit is intended for use within the air conditioning system - specifically the evaporator chamber, refrigerant metering, and blower airflow portions of the HVAC assembly.

The A/C evaporator (Part No. 96457390100) cools the cabin air by absorbing heat from incoming air passing through the HVAC system into the A/C refrigerant circuit. As refrigerant enters the evaporator, it expands and removes heat - providing cold, conditioned air for the cabin.

The blower motors (96457201501 & 96457201601) circulate air across the evaporator core and into the cabin through the ventilation ducts. Reliable blower operation is essential for efficient A/C performance and passenger comfort.

The expansion valve (92857312305) precisely meters refrigerant flow into the evaporator, ensuring the correct pressure and temperature for optimal cooling. An effective expansion valve prevents evaporator freeze-up and reduces strain on the A/C compressor.

High-quality O-ring seals (99970743441 and 99970725141) guarantee leak-free connections between A/C components, maintaining proper refrigerant pressure and system integrity.

Over time, A/C evaporators can develop internal corrosion, refrigerant leaks, or blockages. Age-worn blower motors fail to deliver sufficient airflow, and expansion valves can become clogged or lose metering precision. Faulty O-rings degrade and allow refrigerant to escape. This leads to:
•  Weak cabin cooling
•  Unstable A/C pressure
•  Blower noise or failure
•  Higher compressor load
•  Reduced HVAC efficiency

Replacing these components with OE Match quality parts and genuine Porsche O-rings ensures correct fit, proper refrigerant sealing, and long-lasting air-conditioning performance.

Recommended replacements if you notice:
•  Diminished cooling capacity or warm air from vents
•  Weak or inconsistent blower airflow
•  Refrigerant leaks or low system pressure
•  Excessive blower noise
•  System not reaching cold set temperature
•  During A/C system overhaul or major service

This piston is a core internal engine component that reciprocates in the cylinder bore, converting combustion pressure into mechanical motion via the connecting rod and crankshaft. It also works with piston rings to seal the combustion chamber, manage oil control, and withstand high heat/pressure - helping maintain factory-level performance, durability, and engine dynamics.

Functions & Technical Role:
•  Combustion pressure handling: Converts the force of combustion into linear piston movement
•  Sealing the chamber: Works with piston rings to maintain compression and prevent blow-by
•  Oil control: Cooperates with rings and skirt design to manage oil lubrication

Fitment / Position on Car
  Installed on: Inside the engine block’s cylinder bores
  Location: One per cylinder; typically 6 pistons required for a complete 3.8 L flat-six engine
  Orientation: Works with piston rings, wrist pin, and connecting rod to form the bottom of the combustion chamber

Manufactured using advanced alloy technology and strict quality control standards, MAHLE pistons are engineered to withstand extreme thermal loads and high engine speeds typical of Porsche applications. The piston works in conjunction with piston rings and the connecting rod assembly to convert combustion energy into smooth, reliable crankshaft rotation.

Ideal for engine rebuilds, overhauls, or performance restorations where maintaining factory specifications is essential.

Please note: Pistons are sold individually. Six required per engine.
