Information
Cylinder Head Intake Valve.
Maintain the performance and reliability of your classic Porsche engine with this OE Match cylinder head intake valve. Designed to precisely replicate the original Porsche specification, this valve ensures proper airflow, sealing, and combustion efficiency in early air-cooled engines. Manufactured from high-grade, heat-resistant steel alloy, it delivers outstanding strength, thermal stability, and wear resistance — essential for the demanding environment of Porsche’s horizontally-opposed engines. Each valve is precision-ground for perfect seat contact, ensuring smooth intake flow, consistent compression, and long-term durability.
Fits:
Porsche 911 S/TU/T/E 1965-69
Porsche 914-6 1970-76
Diagram ref no 9.
Function:
The intake valve allows the precise entry of the air-fuel mixture into the combustion chamber. Properly sealing valves are critical for maintaining compression, fuel efficiency, and smooth idle. A high-quality OE Match valve ensures exact timing, optimal airflow, and factory-level performance across the rev range.
Why & When Replacement Matters
Why:
Continuous exposure to heat, carbon build up, and mechanical stress can cause valve face wear, pitting, or bending, leading to loss of compression, rough running, and reduced power.
When:
Replacing with an OE Match intake valve restores engine efficiency, reliability, and preserves the authentic performance character of your classic Porsche.

Why & When Replacement Matters
Why:
Continuous exposure to heat, carbon build up, and mechanical stress can cause valve face wear, pitting, or bending, leading to loss of compression, rough running, and reduced power.
When:
- During engine rebuilds or top-end overhauls
- When compression loss or poor idle is detected
- If valves show visible wear, burn marks, or stem play
- As part of routine maintenance for high-mileage or performance engines
Replacing with an OE Match intake valve restores engine efficiency, reliability, and preserves the authentic performance character of your classic Porsche.
