Oil Filter Bypass Valve

The Chevrolet Performance Oil Filter Bypass Valve (part number 25013759) is an essential component for maintaining optimal oil flow in both stock and modified Chevy engines. This valve is designed to ensure that your engine receives adequate lubrication, particularly under high-pressure conditions where traditional filtration may not suffice.

Featuring a spring-loaded poppet design, this valve opens when oil pressure exceeds a calibrated threshold, typically between 10 and 15 PSI. This mechanism allows unfiltered oil to bypass the filter element, preventing filter collapse and ensuring that vital engine components receive necessary lubrication during cold starts or high-RPM operation.

Ideal for mechanics and automotive enthusiasts, this Chevrolet Performance unit serves as a direct factory replacement for most small-block and big-block Chevy platforms, including LS-series engines. Its robust design resists degradation from thermal cycling and oxidized oil residue, making it a reliable choice for engine longevity.
