What This Product Does
The intake valve controls the entry of the air and fuel mixture into the combustion chamber. When closed, it also contributes to the seal needed to maintain cylinder compression during the engine cycle.
Functions
- Controls intake flow into the combustion chamber
- Helps maintain cylinder sealing and compression
- Supports correct combustion and smooth engine operation
- Replaces a worn or damaged original intake valve
Technical Details
- Product type: engine inlet valve
- Valve dimensions: 10 mm x 130.6 mm
- Quantity required: four; supplied individually
Symptoms of Fault
- Low or uneven cylinder compression
- Rough idle or persistent misfiring
- Reduced engine power
- Pitting, burning or physical damage to the valve face
- Poor sealing identified during compression or leak-down testing
Why Replacement Matters
A worn, burnt or damaged intake valve may no longer seal correctly against its seat, allowing compression to escape and disrupting intake flow. Replacement is commonly carried out during cylinder-head refurbishment or an engine rebuild to restore correct valve operation. The valve seat, guide, spring and associated retaining components should also be inspected before assembly.

Exhaust valves operate under extreme temperatures and repeated combustion cycles, making them one of the most highly stressed components within the engine. Over time, heat, carbon deposits, corrosion, or insufficient lubrication can cause the valve face, stem, or seating surface to wear or burn, leading to poor sealing and reduced engine efficiency. Replacing worn or damaged exhaust valves restores proper combustion sealing and exhaust gas flow, making this OE Match component ideal for routine maintenance, engine repairs, rebuilds, and Porsche restoration projects.
What This Product Does:
- Controls the release of exhaust gases from the combustion chamber.
- Maintains correct cylinder sealing during the combustion cycle.
- Supports efficient engine performance and combustion.
- Helps maintain correct compression and valve timing.
- Restores proper exhaust gas flow.
- Replaces worn, burnt, or damaged original exhaust valves.
- Provides an OE-style fit and dependable quality.
Symptoms Of Wear Or Failure:
- Loss of engine power.
- Reduced engine compression.
- Rough or uneven idle.
- Engine misfires.
- Excessive valve train noise.
- Burnt, pitted, or cracked valve faces.
- Increased exhaust emissions.
- Excessive heat damage or carbon build-up on the valve.
Why Replacement Matters:
- The exhaust valve plays a critical role in allowing spent combustion gases to exit the engine while maintaining an effective seal during compression and combustion. A worn, burnt, or damaged exhaust valve can reduce engine performance, lower compression, increase fuel consumption, and eventually cause serious engine damage if left unresolved.
- Replacing the exhaust valve restores efficient exhaust gas flow, reliable cylinder sealing, and smooth engine operation while helping to protect other valve train components from unnecessary wear. Manufactured as a direct replacement and produced to OE-style specifications, this OE Match engine cylinder head exhaust valve provides the correct fit, dependable quality, and long-lasting durability, making it an ideal choice for Porsche maintenance, engine rebuilds, repairs, and restoration projects.

Operating under constant heat, pressure, and repeated opening and closing cycles, intake valves are subject to gradual wear over time. Carbon build-up, stem wear, valve face erosion, or physical damage can prevent the valve from sealing correctly, reducing engine efficiency and performance. Replacing worn or damaged intake valves restores proper cylinder sealing and airflow, making this OE Match component an excellent choice for routine maintenance, engine repairs, rebuilds, and Porsche restoration projects.
What This Product Does:
- Controls the intake of the air and fuel mixture into the combustion chamber.
- Maintains correct cylinder sealing during the combustion cycle.
- Supports efficient combustion and engine performance.
- Helps deliver smooth power and throttle response.
- Restores correct valve operation during engine rebuilds.
- Replaces worn, burnt, or damaged original intake valves.
- Provides an OE-style fit and dependable quality.
Symptoms Of Wear Or Failure:
- Loss of engine power.
- Rough or uneven idle.
- Reduced engine compression.
- Misfiring cylinders.
- Poor fuel economy.
- Excessive valve train noise.
- Burnt, pitted, or bent valve faces.
- Excessive oil consumption caused by valve-related wear.
Why Replacement Matters:
- The intake valve is a critical component of the engine's valve train, regulating the precise amount of air and fuel entering each cylinder while maintaining an effective seal throughout the combustion cycle. A worn, burnt, or damaged intake valve can reduce compression, lower engine performance, increase fuel consumption, and eventually lead to costly engine damage if left unresolved.
- Replacing the intake valve restores proper airflow, combustion efficiency, and reliable engine performance while helping to protect other valve train components from unnecessary wear. Manufactured as a direct replacement and produced to OE-style specifications, this OE Match engine cylinder head intake valve provides the correct fit, dependable quality, and long-lasting durability, making it an ideal choice for Porsche maintenance, engine rebuilds, repairs, and restoration projects.

Diagram ref no 11
The exhaust valve controls the flow of burnt combustion gases from the cylinder into the exhaust system. Because it operates directly in the combustion chamber, it is subjected to extremely high temperatures and repeated mechanical loading every time the engine runs.
What Does the Exhaust Valve Do?
During the engine's exhaust stroke, the exhaust valve opens to allow burnt gases to leave the combustion chamber. It then closes against the valve seat to seal the cylinder for the next combustion cycle.
Correct sealing is essential for maintaining cylinder compression, efficient combustion and smooth engine performance.
Why Do Exhaust Valves Fail?
Exhaust valves operate in a particularly demanding environment because hot combustion gases pass directly across the valve head and seat.
Over time, deterioration can result from:
- Valve face or seat wear
- Excessive heat
- Burning or pitting of the valve face
- Carbon deposits
- Valve stem or guide wear
- Incorrect valve clearances
- Poor valve seating
- Corrosion during long periods of storage
A valve that no longer seals correctly can cause loss of compression and poor engine performance.
When Should It Be Replaced?
Replacement should be considered if inspection identifies a burnt, cracked, bent, excessively worn or badly pitted valve.
Possible symptoms of valve or cylinder head problems
include:
- Low cylinder compression
- Misfiring or uneven running
- Reduced engine performance
- Poor combustion
- Excessive valve train noise
- Failed compression or leak-down testing
The condition of the exhaust valves should always be assessed during a cylinder head overhaul or major engine rebuild.
Checks During Replacement
When replacing an exhaust valve, also inspect:
- Exhaust valve seat
- Valve guide
- Valve spring
- Valve collets and retainers
- Rocker arm and adjuster
- Cylinder head condition
- Remaining inlet and exhaust valves
Valve guide clearance and valve seat condition should be checked carefully before fitting a new valve.
