Cylinder kit, VW 94MM 2.0 Type 4. Porsche 914 ❭ VW9400T4L
- Porsche 914 (1970-1976)
94mm Cylinder Kit – Set of 4
Restore the power, compression and reliability of your classic air-cooled engine with this OE Match 94mm Cylinder Kit, designed for 2000cc Volkswagen Type 4 engines fitted to the Porsche 914.
Fits:
- Porsche 914 (1970-1976)
Manufactured from high-quality cast iron, these replacement cylinders are precision machined to OE specifications and require no additional machining before installation, making them an excellent choice for both professional engine builders and home restorations. The robust cast iron construction offers outstanding wear resistance, excellent heat dissipation and long service life, helping to restore factory engine performance and reliability.
Whether you're rebuilding a worn engine or undertaking a complete restoration, this OE Match cylinder kit delivers dependable quality and OE-style fitment.
What Do Engine Cylinders Do?
Engine cylinders provide the precision-machined bore in which the pistons travel, creating the compression required for efficient combustion and power production.
Their primary functions include:
- Guiding piston movement
- Maintaining engine compression
- Providing a durable wear surface
- Dissipating combustion heat
- Supporting smooth, efficient engine operation
Healthy cylinders are essential for maintaining power, fuel efficiency and correct oil control.
Why Do Engine Cylinders Wear Out?
After years of service, continual piston movement and repeated heat cycles gradually wear the cylinder bores.
Common causes include:
- High engine mileage
- Poor lubrication
- Engine overheating
- Worn piston rings
- Dirt or debris entering the engine
- Corrosion following long-term storage
As cylinder wear increases, engine compression falls, oil consumption rises and overall performance declines.
When Should They Be Replaced?
Cylinder replacement is recommended if:
- Compression readings are below specification
- Cylinder bores are worn, tapered or scored
- Oil consumption has noticeably increased
- Excessive piston-to-cylinder clearance is measured
- The engine is undergoing a complete rebuild
- Heat damage or corrosion is present
Replacing worn cylinders during an engine rebuild restores compression, improves reliability and helps return the engine to its original performance.
Porsche 914 Type 4 Engine Components
The 2.0-litre Type 4 engine relies on precision-engineered cylinders to maintain compression, control oil consumption and deliver the performance expected from Porsche's air-cooled flat-four. As engines accumulate mileage, cylinder wear can reduce power, increase oil consumption and affect overall reliability.
Replacing worn cylinders during an engine rebuild restores engine efficiency while helping extend the life of pistons, piston rings and other internal components. OE Match cast iron cylinders are manufactured to factory standards, providing dependable performance and direct installation without the need for additional machining.
