IMPORTANT: This KraftWerks Blow Off Valve (BOV) is ONLY designed to work with KraftWerks Supercharger Kits and is only needed on ones that do not already come with a BOV or bypass valve.

This is the NEW billet version.

Blow off valve performance is crucial for a properly performing forced induction system. KraftWerks blow-off valves are designed to outperform OEM and others while providing superior durability and being cost effective as well. Finished with black powder coating, they offer a stealthy look, with a heavy duty, CNC billet aluminum body and components and a large piston for high flow and quick response. KraftWerks Blow Off Valves are highly efficient, control compressor surge, and offer superior response to fluctuation in pressure. This new KraftWerks BOV can aid in minimizing bearing failure and supercharger or turbocharger wear. Unlike other BOVs, KraftWerks does not utilize a diaphragm as they tend to leak or tear.
