- Common defects from incorrect application include noise, premature wear, leaks, or fitment quirks if the wrong variant is selected or fitted with old seals/hardware.
- Watch for symptoms such as unusual noises, early wear, or repeat failures after recent work, which can indicate mismatched parts or supporting items left worn.
- Always cross-check OEM part numbers, read model-year notes, and verify compatibility before ordering.
- For safety-critical components, confirm specification and fitment carefully and have installation checked by a competent technician.
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, longer stopping distances, squealing, pulling to one side, warning lights and visible wear to discs and pads.
Brake Pad Wear Sensors — Brake pad wear sensors are replaced when pads are renewed or when warning lights indicate a broken or worn sensor. Symptoms include brake wear warnings even with new pads, damaged sensor cables, or broken clips around the caliper area.
Engine Electrical — Engine electrical parts are changed when there are starting, charging, ignition, or sensor-related faults that affect drivability and reliability, such as intermittent no-start, misfires, rough idle, poor charging, warning lights or heat-soak failures.
Service Parts — Service parts are replaced as routine maintenance to keep the engine and systems reliable, efficient, and protected, often resolving hard starting, rough idle, poor fuel economy and warning lights caused by clogged filters or worn ignition components.
Service Kits — Service kits bundle key service components to simplify maintenance and set the car back to a known baseline, especially useful when catching up on overdue servicing or dealing with general sluggish running, inconsistent idle and reduced performance.
- For brake parts, confirm whether items are OE-equivalent replacements or performance upgrades and check if new fitting kits and sensors are required.
- On service items and kits, match the kit to your exact Porsche model, engine and year, and review what is included so you can add any extra “while you are there” parts.

What exhaust valve does:
• Seals the combustion chamber on the exhaust side, opening and closing at the correct times to allow exhaust gases to exit
• The internal sodium enhances heat transfer, reducing valve temperature, helping prevent distortion or burning
• Works in tandem with valve springs, guides, and seats to maintain consistent cylinder head performance
Over time, exhaust valves undergo extreme heat cycles, which can lead to wear, bending, warping, or pitting on the sealing face. A faulty or damaged exhaust valve can lead to compression loss, misfires, reduced power, excessive smoking, or engine damage. Replacement improves reliability, restores engine efficiency, and ensures long life under high temperature conditions
• It fits in the cylinder head’s exhaust valve seat for Porsche 964 the exhaust port side of each combustion chamber
• The valve stem goes through the valve guide in the head, and the head of the valve seals against the exhaust seat when closed, with its tip actuated by the rocker or cam mechanism.

The exhaust valve is located in the cylinder head as part of the engine’s valve train. With every combustion cycle, it opens to release exhaust gases and closes again to preserve compression. Built to endure extreme heat, pressure, and constant motion, it plays a vital role in maintaining engine performance, efficiency, and emissions control.
Over time, exhaust valves can wear or deform due to heat, carbon deposits, or mechanical stress. When they no longer seal properly, exhaust pressure can leak past the valve seat, reducing compression, power, and efficiency. In severe cases, a failing exhaust valve can lead to misfires, rough running, or damage to the cylinder head.
You should consider replacing the exhaust valve if any of the following occur:
• Loss of engine power, especially at higher RPMs
• Rough idle or misfires
• Exhaust smoke or unusual noise from the cylinder head
• Compression test reveals a weak cylinder
• When rebuilding or overhauling the engine or cylinder head
• After excessive heat exposure or in engines with high mileage
Replacing the valve ensures precise fit, proper sealing, and long-term durability — critical for restoring engine performance and preventing further damage.

Correct flywheel bolts are critical because they maintain the integrity of the crank-to-flywheel joint - supporting smooth power transfer, stable clutch operation, and long-term reliability. This OE Match version is designed for direct replacement during clutch/flywheel service and engine rebuild work.
Function: These bolts thread into the crankshaft flange and clamp the flywheel in place, ensuring accurate alignment and a secure interface between engine and clutch assembly. Proper bolt specification supports consistent torque retention and helps protect the flywheel, crank flange, and clutch components from vibration-related wear.
Flywheel bolts operate under high stress and can fatigue, stretch, or lose torque retention after removal and re-torque cycles. Replacing them with correct OE Match bolts helps ensure proper clamp load, reduces the risk of loosening, and protects expensive components from damage caused by flywheel movement.
When to replace:
• During clutch replacement or flywheel removal
• During engine rebuilds or rear main seal work requiring flywheel removal
• If bolts show thread damage, corrosion, or signs of stretching
• When service procedure specifies new bolts on reassembly
• Any time correct torque cannot be reliably achieved

Provides the critical clamping force between crankshaft flange and flywheel. Correct bolt stretch and friction are essential to prevent loosening, fretting, or flywheel run-out that can cause vibration, starter engagement issues, or clutch damage.
Over time, flywheel bolts can stretch, corrode, or lose their clamping strength due to repeated torque cycles and heat exposure. A weakened or reused bolt may fail to maintain the necessary preload, risking vibration, misalignment, or flywheel damage.
Replace the flywheel bolts when:
• Performing a clutch or flywheel replacement (most Porsche bolts are single-use torque-to-yield).
• Bolts show signs of corrosion, thread damage, or head wear.
• The factory service procedure specifies new bolts for reassembly.
Installing a new bolt set ensures secure fastening, correct torque tension, and long-term drivetrain reliability.

Installed through the clutch pressure plate into the flywheel, this bolt spreads load evenly and resists loosening under vibration and torque. Its material and geometry are matched to the factory specification so that it maintains clamping force throughout heat cycles and driving loads, helping prevent premature wear and ensuring stable clutch diaphragm performance.
Clutch bolts are subject to high clamping forces, heat cycles, and torque loads. Over time, original hardware can stretch, corrode, or fatigue, all of which can lead to compromised load retention. Reusing old or damaged fasteners increases the risk of clutch slip, uneven pressure plate contact, or flange failure. Installing fresh bolts helps restore correct clamping integrity and reduces the risk of future clutch-related issues.
When to replace:
• During clutch replacement or overhaul
• If original bolts show corrosion, stripping, or rounding
• After removal during transmission service
• Preventive maintenance in performance or high-mileage vehicles
