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.

Porsche 944 / 924S High-Pressure Fuel Hose XL – Safety Upgrade
Prevent Fuel Leaks and Reduce Engine Bay Fire Risk
One of the most common causes of engine bay fires in the
Porsche 944 is failure of the main high-pressure fuel line. Over time, the
original hose ages, hardens and develops cracks. When this line leaks, fuel can
drip directly onto the hot exhaust manifold, creating a serious fire hazard.
Fits:
- Porsche 924S 2.5L 1986-87
- Porsche 924S 2.5L 1988
- Porsche 944 2.5L 8V 1982-87
- Porsche 944 2.7L 8V 1988-89
- Porsche 944S 2.5L 16V 1987-88
- Porsche 944S2 3.0L 16V 1989-91
- Porsche 944 Turbo 2.5L 8V 1985-88
- Porsche 944 Turbo 2.5L 8V 1989-91
- Porsche 944 Turbo S 2.5L 8V 1988
This upgraded XL high-pressure fuel hose is designed to eliminate that risk by improving routing and adding additional heat protection.
What the Main Fuel Hose Does
The main high-pressure fuel hose delivers pressurised fuel from the fuel rail and fuel system to the engine. It operates under constant pressure and high temperatures inside the engine bay.
Its function is critical to:
- Supplying consistent fuel pressure
- Maintaining proper engine performance
- Ensuring safe fuel delivery under load
Because this hose sits near the exhaust system in factory configuration, deterioration can quickly become dangerous.
Why Original Fuel Hoses Fail
Over decades of use, factory fuel hoses commonly suffer
from:
- Age-related rubber cracking
- Heat exposure from the exhaust manifold
- Ethanol content in modern fuels
- Internal degradation under pressure
- Sudden splitting without warning
Fuel leakage can happen unexpectedly and escalate quickly.
Why You Should Upgrade to the XL Version
This XL high-pressure fuel hose has been redesigned for improved safety and longevity.
Key advantages include:
- Extra length to reroute the hose along the top of the bulkhead
- Avoids running directly over the hot exhaust
- Black heat-resistant outer sheath for added protection
- Improved routing reduces stress on fuel rail connections
- Helps prevent cracking at fuel rail fittings
By routing the hose away from the exhaust and securing it along the bulkhead, the risk of fuel contacting high heat components is significantly reduced.
In early models and 924S variants, the extended length allows cleaner routing under the spray piece, improving both appearance and reliability.
A vehicle lift is required for installation.
When You Should Replace Your Fuel Line
You should replace the main fuel hose if:
- The original line has never been replaced
- You notice fuel smell in the engine bay
- The hose shows cracking or brittleness
- You are restoring or maintaining a classic 944 or 924S
- You want preventative fire protection
Eventually, every original hose will require replacement. Upgrading now protects both your vehicle and your investment.
Key Benefits at a Glance
- Direct replacement high-pressure fuel hose
- Extra-long design for safer routing
- Avoids contact with hot exhaust components
- Heat-resistant outer protective sheath
- Suitable for all 944 years and 924S
- Helps prevent fuel rail connection cracking
- Ideal preventative safety upgrade

Porsche 928 Centre Console Trim - Early Three Gauge Type
Reproduction Replacement for NLA Original Part
This early three gauge centre console trim is a precision-engineered replacement designed specifically for Porsche 928 models from 1978 to 1979. Originally supplied by Porsche but now NLA (No Longer Available), this part has become extremely difficult to source in usable condition.
Fits:
- Porsche 928 4.5L 1978-82
Diagram Ref No 7
To solve this issue, the original component was 3D scanned and carefully reproduced. After refinement and minor design improvements, the result is a high-quality reproduction that fits exceptionally well, including vehicles with leather dashboard trims.
What the Centre Console Trim Does
The centre console trim in the early Porsche 928 serves both
functional and aesthetic purposes. It:
- Houses and frames the three central gauges
- Surrounds the radio aperture
- Integrates visually with the dashboard design
- Provides structural support for console-mounted components
- Maintains the clean and distinctive early 928 interior layout
In early 928 models, the three gauge configuration is a defining feature of the interior. Maintaining the correct console trim preserves originality and classic styling.
Why Centre Console Trims Fail on Early 928 Models
Due to age and material fatigue, original centre console
trims often suffer from:
- Cracking due to heat exposure
- Warping from prolonged sun damage
- Brittleness from ageing plastics
- Breakage around mounting points
- Damage from radio installations
- Deformation during removal or restoration work
Because Porsche discontinued this part, used originals are rare and often in poor condition.
This reproduction trim solves a long-standing restoration challenge for early 928 owners.
Improved Reproduction with Practical Benefits
This reproduction console trim has been developed using
modern manufacturing techniques:
- 3D scanned from an original part
- Modified for improved fitment
- Manufactured from strong, durable material
- Compatible with leather dashboard interiors
- Can be modified to suit later size radios if required
The material is robust enough to allow careful trimming of the radio aperture to accommodate upgraded head units, making it suitable for both restoration and subtle modernisation projects.
When You Should Replace the Centre Console Trim
You should consider replacing the centre console trim if:
- The original part is cracked or warped
- Mounting tabs are broken
- The console does not sit flush with the dashboard
- The radio aperture has been damaged
- You are restoring a 1978–1979 Porsche 928
- You are upgrading interior components while maintaining factory styling

Mechanical Rocker Arm Conversion Set - High-Performance Valve Train Upgrade
The Mechanical Rocker Arm Conversion Set is a
precision-engineered valve train upgrade for Porsche 993, 993 Turbo and GT2
engines. This conversion replaces the original hydraulic lifter system with a mechanical
rocker arm setup featuring oil-lubricated rocker shafts, delivering
improved valve control, reliability, and performance at high engine speeds.
Fits:
Designed for high-performance road, motorsport, and track-focused engines, this conversion eliminates the limitations associated with hydraulic lifters, particularly under sustained high RPM and extreme thermal loads. By adopting mechanically actuated rocker arms with direct oil lubrication, engine builders gain greater consistency, improved durability, and enhanced camshaft control.
This system is widely used in competition builds, high-output street engines, and applications where precise valve timing and stability are critical.
What Does the Mechanical Rocker Arm Conversion Do?
This conversion fundamentally improves how the valve train operates under load.
Core Functions:
- Replaces hydraulic lifters with mechanically actuated rocker arms.
- Provides direct, oil-lubricated rocker shaft operation.
- Improves valve control and timing accuracy at high RPM.
- Reduces valve float and lifter pump-up issues.
- Enhances reliability in high-performance and motorsport applications.
By removing hydraulic compensation, the valve train responds more precisely to camshaft profiles, making this conversion ideal for aggressive cam setups and sustained high-speed operation.
Why Do Hydraulic Valve Train Components Fail?
Hydraulic lifter systems are designed for comfort and noise reduction, but they become a limitation in high-performance environments.
Common Failure or Limitation Causes Include:
- Lifter
pump-up at high RPM, causing valve float.
- Oil
aeration or pressure fluctuations, reducing lifter effectiveness.
- Thermal
breakdown, leading to inconsistent valve timing.
- Wear
or collapse of hydraulic elements over time.
- Reduced reliability under track or motorsport conditions.
These issues can compromise performance, cause misfires, or lead to accelerated valve train wear.
Why Replace or Upgrade to a Mechanical Rocker Arm System?
Upgrading to a mechanical rocker arm system provides a robust, performance-focused solution for demanding engines.
Key Benefits:
- Consistent valve operation at high engine speeds.
- Improved durability compared with hydraulic systems.
- Oil-lubricated rocker shafts for reduced friction and wear.
- Ideal for high-lift or motorsport camshaft profiles.
- Enhanced throttle response and power delivery.
- Proven solution for track, race, and high-output road engines.
This conversion is a cornerstone upgrade for Porsche 993-based performance engines where reliability and precision are paramount.

Porsche 992 GT3 - 2019 Onwards
Only for Optional Magnesium wheels (PR - 56R)
Sold as a pair
Premium Carbon fiber aero discs are aerodynamic wheel covers for the Porsche 992 GT3 with Magnesium wheels
These improve the airflow around the rear of the car and make your rear wing work better. Some say you can reduce the wing angle by 2 degrees and fit these and still keep the same downforce numbers.
The covers help to manage the airflow around the rear wing, reducing vortices and drag, therefore offering an improvement to the aero efficiency and looks at the same time. A perfect marriage of form and function.
Weighing in at only 380 grams each, the wheel covers are made by hand from prepreg carbon of the highest quality. Using composite molds and baked to perfection. Our mounting structure is made out of carbon prepreg that is lightweight but gives the structures the rigidity they need and then some. They are hand sanded and polished to a mirror like shine. We then protect them with a UV resistant epoxy that is backed by our 5 year warranty against cracking and yellowing. No questions asked.
We supply all sets with titanium bolts and all mounting and wheel protection hardware.
Key Features:
- Hand made from the highest quality pre-preg carbon fiber
- Improved design and aesthetics
- Enhanced aerodynamic performance
- Titanium bolts included
- Included PPF Pre-Cuts and Nylon wheel shields to protect wheels
