Information
Engine cylinder head exhaust valve kit.
The OE Match exhaust valve set includes 12 precision-engineered exhaust valves designed for Porsche 996 Turbo, 996 GT2, 997 Turbo and 997 GT2 models. These valves are installed in the cylinder heads and control the release of exhaust gases from the combustion chambers during the engine’s exhaust cycle.
SET OF 12 exhaust valves
Fits:
Porsche 996 Turbo / GT2 2001 - 2005
Porsche 997.1 Turbo / GT2 3.6L 2007 - 2009
Porsche 997.2 GT2 RS 3.6L 2011
Diagram ref no 3.
Exhaust valves are a critical component of the engine valve train. Each valve sits in the cylinder head and is operated by the camshaft through the valve train mechanism. During the combustion cycle, the valve opens to allow burnt gases to exit the cylinder and then closes to seal the chamber for the next intake and compression phases.
The OE Match set contains 12 exhaust valves, which corresponds to the number required for a complete flat-six turbo engine used in Porsche 996 and 997 Turbo models.
These valves are engineered to withstand the high temperatures and pressures generated by turbocharged combustion while maintaining precise sealing and smooth valve train operation.
The exhaust valves open during the exhaust stroke to release burnt gases from the combustion chamber and close to maintain compression during the compression and power strokes. This process ensures efficient combustion and optimal engine performance.
Replacing worn valves during engine servicing or rebuild ensures consistent sealing across all cylinders and reliable engine operation.
Exhaust valves operate under extreme temperatures and constant mechanical stress. Over time they can develop wear, carbon buildup or valve face damage, which may cause compression loss or reduced engine efficiency. Replacing the valves as a full set ensures balanced performance across all cylinders and helps maintain reliable engine operation.
Consider replacing the exhaust valves when:
• Performing a cylinder head rebuild
• Engine compression is low or uneven
• Valves show burning, pitting or excessive wear
• During a major engine overhaul or restoration

What This Product Does:
- Controls the intake of air and fuel into the combustion chamber.
- Opens and closes in precise timing with engine operation.
- Maintains an effective seal during compression and combustion cycles.
- Supports efficient airflow and engine breathing.
- Helps maximise engine performance and throttle response.
- Contributes to fuel efficiency and emissions control.
- Forms a critical part of the engine valvetrain system.
Symptoms Of Wear Or Failure:
- Loss of engine power and performance.
- Rough idle or uneven engine running.
- Engine misfires.
- Poor throttle response and acceleration.
- Increased fuel consumption.
- Low compression in the affected cylinder.
- Difficulty starting the engine.
- Ticking or tapping noises from the cylinder head.
- Engine management warning lights or fault codes.
- Failed compression or leak-down test results.
Why Replacement Matters:
- Inlet valves are subjected to continuous opening and closing cycles while being exposed to heat, combustion by-products and airflow turbulence. Over time, valves can become worn, bent, burnt, carbon-contaminated or develop sealing issues that negatively affect engine efficiency and performance.
- A damaged inlet valve can restrict airflow into the combustion chamber, resulting in poor combustion, reduced power output and increased fuel consumption. If left unresolved, valve-related problems can contribute to compression loss and may cause additional wear to valve seats, cylinder heads and other internal engine components.
- Replacing a worn or damaged inlet valve restores proper airflow, improves combustion efficiency and helps maintain optimal engine performance. An OE Match replacement provides factory-style fitment, precision manufacturing and long-term durability, ensuring reliable operation and helping protect your Porsche engine from premature wear and costly repairs.
