42MM Blow Off Valve – N54

Product Details

Blow off valves are pressure relief systems that exist in most turbocharged engines. They allow compressed air to vent to the atmosphere, which saves wear and tear on your turbo and your engine. The Active Autowerke BOV is a pull-style BOV meant for high 500+ WHP BMWs. This BOV is made with an all aluminum cast body with a large single stage, steel pull-type valve to handle the extreme pressure discharge that comes with high boost applications. Engineered to hold up to 43 PSI.

Not for sale or use in the state of California on any pollution-controlled vehicle as per the California Air Resources Board.
