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

Information
Exhaust valve, (Sodium-filled).
This is a sodium-filled exhaust valve designed to Porsche’s original specifications, as used in 964 Carrera (C2 / C4) 3.6L engines (1990–94). The sodium fill helps dissipate heat from the valve head into the valve stem, improving thermal management under exhaust conditions.
Sold each, 6 required per car.
Fits:
Porsche 964 Carrera 2 / Carrera 4 3.6L 1989 - 1994 (M64.01 / M64.02)
Porsche 964 RS Carrera 3.6L 1991 - 1994 (M96.03)
Diagram Ref No 12.
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.

Function:
The inlet valve controls the flow of air-fuel mixture into the combustion chamber. Proper sealing and timing are essential for maintaining compression, combustion efficiency, and overall power output. A high-quality OE Match valve ensures consistent intake airflow, reliable operation, and long engine life.
Why & When Replacement Matters
Why: Over time, inlet valves experience wear from heat, carbon build up, and mechanical stress, which can lead to reduced compression, power loss, and rough engine operation.
When: During engine rebuilds or cylinder head servicing If there are signs of valve leakage, pitting, or stem wear. When experiencing loss of power, misfires, or compression imbalance. As preventive maintenance on high-mileage engines or performance builds.
