Koblenz
Koblenz for Porsche
Koblenz parts for Porsche models are typically chosen as practical repair and refurbishment components that help restore function and day-to-day usability. At Design911 you can browse Koblenz alongside other brands, then filter by Porsche model and system to narrow down to what you need.
A Quick Look at Koblenz
Koblenz 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 Koblenz is listed for Porsche, use the supplied model coverage and OE references to confirm suitability. Check details that commonly affect fitment such as model year, side or position, and connector or mounting type where relevant.
- Typical reasons to choose these parts include resolving age-related deterioration, replacing worn mechanical components, and getting the car reliably back on the road without overcomplicating the job.
- Common symptoms that lead to replacement include noise, vibration, premature wear, or intermittent operation, often linked to incorrect prior fitment or associated parts not being changed at the same time.
- Always match Porsche model/year and cross-check part numbers where possible, and plan to renew related seals, hardware, or consumables during the same job.
- Before replacing parts, diagnose the root cause carefully — a single new component will not cure issues caused by wider system wear, misalignment, or installation problems.
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.
Engine Rebuild Parts — Engine rebuild parts from Koblenz are used during planned strip-downs or when symptoms point to internal wear, such as low compression, excessive oil use, persistent leaks, or abnormal noises. Where applicable, they are renewed together with related bearings, chains, guides, gaskets, and hardware while the engine is apart to avoid repeat labour and to improve reliability after the rebuild.
- Before committing to major engine work, use compression and leak-down testing, oil and filter inspection, and borescope checks to confirm that a rebuild and new parts are justified.
- When the engine is open, many specialists also replace hard-to-reach wear items "while you are in there" to reduce the risk of further tear-downs.
Engine Cylinders / Liners / Pistons — Cylinders, liners, and pistons are core components that are replaced when scoring, wear, or damage prevents proper sealing and reliable running. In Porsche rebuilds they are typically changed for issues such as low compression, excessive oil consumption, piston slap, or after overheating or detonation events, and may also be upgraded where changes in displacement or durability are desired.
- Decisions on these parts should follow measured checks for scoring, ovality, and ring condition, plus an assessment of the oiling and cooling systems that may have caused the damage.
- Ensure pistons, rings, and cylinders are correctly matched as a set and that clearances are within specification during assembly.
Camshafts — Camshafts from Koblenz are fitted when existing cams show wear, pitting, or damage, or when changing profiles to alter how the Porsche engine delivers its power. Replacement is common where there is top-end noise linked to cam wear, or during performance and reliability-focused valvetrain rebuilds.
- Oil quality and pressure are critical — cam wear is often linked to lubrication issues or debris in the oil, so the root cause should be addressed at the same time.
- New camshafts are often installed with fresh followers or rockers to prevent accelerated wear on the new lobes.
Interior & Accessories — Koblenz interior parts and accessories are typically used to replace worn or damaged trim and touch points, or to support refurbishment projects where the Porsche cabin is being refreshed. They help restore correct fit and function and can improve day-to-day practicality without significantly changing the character of the car.
- Expect to address common age-related issues such as broken clips, rattling panels, worn finishes, or sticky switches when refurbishing the interior.
- Use appropriate trim tools and replace missing or damaged fasteners during installation to minimise new squeaks or rattles.
Dial Faces — Dial faces associated with Koblenz-supported instrument work are generally used during cluster refurbishment to restore legibility and appearance or to refresh tired original parts. They are typically replaced when markings have faded, peeled, or warped, or when the style is being updated to match a retrimmed interior.
- Take care when removing and refitting needles, as this can affect how accurately the gauges read if not positioned correctly.
- Work cleanly to avoid dust or fingerprints under the dial face, which can be very noticeable once the cluster is reassembled.

Repair is easy to do for someone with relatively little mechanical experience.
With this set you can repair both sides

When disassembling the fog/driving lamp unit, the mounting bolts often break off due to rust or the lamp housing fastening points break off and the metal inserts in the original housing get stuck due to corrosion and cannot be removed. Drilling out the metal inserts is almost impossible and takes a lot of time.
This problem has been solved with this new lamp housing, so no more trouble with rusted bolts. There are no metal inserts in this fog lamp housing that can rust and the housing is extremely strong.
The original housing is no longer available.
Note: The fog lamp housing is suitable for both the left and the right hand side.
The drain on the back can be disassembled from the old housing and mounted on the new one.

These bushes serve as replacements for the original items and last a lifetime.
The original rubber bushes often break (due to oil leakage from the engine block) and cause play in the steering rack. This can lead to vague steering and tyre wear, which is not good for the driving characteristics.
This problem can be solved by replacing them with these bushes. They are made of high quality aluminium and ensure that the play is completely eliminated so that you can steer tighter through the bend.
Easy to install without having to completely dismantle the steering rack.
Kit contains four bushes.
Features:
- No more play on the steering rack
- Improved driving characteristics due to more direct steering
- Lasts a lifetime
- Easy assembly; steering rack does not need to be disassembled
- Alignment not necessary
- With assembly instructions
- Black anodised to prevent corrosion

The mounting rings for the door speakers grilles are often broken due to age. Gluing does not work very well because the rings are screwed on.
These rings are not available new anymore in the original version, which is why we have redesigned and produced these speaker rings.
The rings are an exact copy of the original in shape and colour and fit directly on the original speakers.
They are equipped with screw thread and you can loosen them by a turning movement.
To replace the rings, all you have to do is swop the speaker grille over.
Set contains:
Two rings for one door panel

Almost every automatic 928 will suffers from loose and cracked selector handles - check for yourself.
The shifter gets cracks in the base and therefore starts to feel a bit loose so slide the rubber off the foot and check the shifter.
The base of the shifter becomes loose where it is mounted and we have even encountered this problem on a 1995 928 GTS.
To save buying an expensive new item, we have developed a mounting block that fits perfectly around the bottom and serves as an extra reinforcement for the gear lever.
By clamping it with the help of the supplied, extended bolts, there is less force on the plastic so it will not break so easily.
Advice:
We advise to install this block as a preventive measure before it is really too late.
Set contains:
1 x Cube automatic gearshift
2 x Mounting bolts

Does your Alternator / Air Con multi belt always squeak?
By fitting this kit you can solve this problem with the addition of an extra pulley.
The multi-ribbed belt has a better grip on the air conditioning pump and alternator, so the chance of slipping and squeaking is greatly reduced.
This is because the extra roller provides extra contact surface on the pulley of the A/C pump.
The additional idler pulley is easy fit to the alternator mounting with the bolt supplied.
Kit contains:
• Multi belt
• Idler pulley
• Spacer for the idler pulley
• Bolt
• Rings
• Nut
