Product Information
The OE Match exhaust valve is a precision engine component designed for Porsche 911 (993) Carrera models equipped with early 3.6L engines. It is installed in the cylinder head and forms part of the valve train responsible for controlling the flow of exhaust gases from the combustion chamber to the exhaust system.
Sold individually, 6 required per vehicle
Fits:
Porsche 993 C2 / C4 3.6L 1993 - 1995
* with Engine codes: M64.05 / M64.06 / M64.07 / M64.08
Diagram Ref No 10
The OE Match version of part number 99310541901 is designed for pre-Varioram Porsche 993 engines used in early Carrera models. It is engineered with the correct stem diameter, valve head size and material specification to withstand the extreme temperatures and stresses experienced in high-performance air-cooled engines.
The exhaust valve regulates the release of burnt gases from the combustion chamber. When opened at the correct time by the camshaft, it allows exhaust gases to exit the cylinder and enter the exhaust system, preparing the chamber for the next intake cycle.
Maintaining properly functioning valves is essential for efficient combustion, engine power and reliable operation.
Exhaust valves operate under extremely high temperatures and continuous mechanical stress. Over time they may wear, warp or suffer from carbon buildup, which can lead to compression loss, poor engine performance or valve train noise. Replacing worn valves during engine service or rebuild ensures proper combustion sealing and reliable engine operation.
Consider replacing the exhaust valve if you notice:
• Loss of compression or engine power
• Excessive valve train noise
• Burnt or worn valve surfaces
• During cylinder head rebuild or engine overhaul
