Turbosmart BOV Supersonic Subaru WRX/STI

The Turbosmart Bov5 is a 38mm positive-seal piston-style valve, engineered with our motorsport-proven boost-balance technology. This means that the more boost you apply, the better it seals – it's as simple as that! Crafted from billet aluminum and meticulously hand-assembled with a precision-matched piston, each valve undergoes rigorous testing to ensure correct seal and operation before shipping. Capable of bypassing up to 800HP worth of air, it's a powerhouse performer. The Supersonic Bov5 is all about noise, flow, and venting to the atmosphere. Ideal for vehicles without Air Flow Meters, it features a single large trumpet for maximum presence.
