Information
Engine cylinder head inlet valve.
Manufactured to OEM specifications, this valve matches the factory dimensions, seat angle, and stem diameter for perfect sealing and valve timing accuracy. Built from high-grade heat-resistant steel, it delivers excellent thermal stability and wear resistance, ideal for the demanding environment of Porsche’s high-revving flat-six engines.
Fits:
Valve stem diameter 9,00 mm
Length 110,10 mm
Valve seat angle 45 °
Diagram Ref No 9.
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.
