Information
Engine cylinder head exhaust valve.
The OE Match exhaust valve is a precision engine component used in the cylinder heads of Porsche 911 Turbo and GT2 models. It is responsible for controlling the release of exhaust gases from the combustion chamber during the engine’s exhaust cycle.
Sold individually, 12 exhaust valves required per engine (one per cylinder).
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.
The exhaust valve is a key element of the engine valve train system. It sits inside the cylinder head and works with the camshaft, valve springs and lifters to regulate the flow of gases in and out of the engine.
This OE Match version follows the original Porsche design, providing the correct stem diameter, valve head geometry and sealing surface required for proper installation and reliable performance.
During engine operation, the exhaust valve opens to allow burnt gases to exit the combustion chamber and enter the exhaust manifold. It then closes to seal the cylinder during the compression and power strokes.
Properly functioning exhaust valves are essential for maintaining engine compression, combustion efficiency and turbocharger performance.
Function
• Exhaust Gas Control: Releases combustion gases from the cylinder
• Combustion Sealing: Closes to maintain compression during the power cycle
• Engine Performance: Supports efficient airflow and combustion
• Valve Train Operation: Works with camshaft, lifters and valve springs
Exhaust valves operate under extremely high heat and mechanical stress. Over time they can develop wear, carbon buildup, or valve face damage, which may lead to compression loss, reduced engine performance or valve train noise. Replacing worn valves during engine servicing helps maintain proper sealing, stable combustion and reliable turbocharged performance.
Consider replacing the exhaust valve when:
• Performing a cylinder head rebuild
• Engine compression is low or uneven
• Valves show burning, pitting or wear
• During major engine overhaul or restoration
