Blow Off Valves
With a simple adjustment (no tool required) you can change the blow off sound of your turbocharged engine - from an ear-piercing whistle to a more subdued whoosh.
The BOW300 has small ports that change the resonance of the blow off air depending on their alignment. The BOS360 is our more traditional blow off valve. Both models are made from high quality billet aluminum, powder coated, and mount easily with a single flange that can be welded to any aluminum charge pipe or hooked to a silicone coupler. They will not leak under high boost pressure or open at idle, to minimize stress on your turbocharger.
