- Porsche 911 1965-1968 2.0L / 912 SWB (F)
- Porsche 914 (1970-1976)
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.
Fits:
Porsche 911 S/TU/T/E 1965 - 1969
Porsche 914-6 1970 - 1976
Diagram ref no 9.
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.
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:
- 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.

The exhaust valve opens and closes in time with the camshaft to release burnt gases after combustion. A correctly sealing valve helps maintain compression, stable idle, clean running, and consistent performance.

Porsche 914-6 1970 - 1976
Diagram ref no 10
This valve forms a gas-tight seal against the valve seat to contain combustion pressure, then opens to allow exhaust flow out of the cylinder. Because exhaust valves operate under high heat, correct material quality and precise machining are critical for longevity and reliable sealing
A worn, pitted, or burnt exhaust valve can cause compression loss, misfires, poor performance, and potentially lead to costly cylinder head damage if ignored. Replacing valves during a rebuild helps restore correct sealing and reliable operation under heat load.
When to replace:
• Low compression / leak-down points to valve sealing issues
• Burnt valve symptoms (misfire, rough idle, power loss)
• Visible pitting, tuliping, or seat damage during teardown
• Excessive valve stem wear found during head inspection
• During cylinder head overhaul or full engine rebuild
