Adjustable Oil Pressure Relief Valve Screw - Type 1 Engines

Adjustable oil pressure relief valve kit for Volkswagen Type 1 aircooled engines. This performance upgrade replaces the original oil pressure relief valve plug and allows oil pressure to be fine-tuned by simply adjusting the preload on the relief valve spring using the built-in Allen screw.

Ideal for performance engines, stroker builds and engines fitted with aftermarket oil pumps, this kit allows precise adjustment of the oil pressure setting to suit your engine combination and operating conditions. By increasing or decreasing spring tension, the oil pressure relief point can be altered without changing springs or dismantling the engine.

Suitable for both single relief and dual relief Type 1 crankcases.

Manufactured from high quality materials and designed as a direct replacement for the original relief valve plug.
