Turbosmart BOV Supersonic Mazda/Subaru -Blue

The Bov5 from Turbosmart is a 38mm positive-seal piston style valve based on our motorsport proven boost-balance technology which means the more boost you feed this valve, the better it seals - Simple as that! Manufactured from Billet Aluminum and hand assembled with a precision matched piston for maximum possible response, each and every valve is tested to ensure correct seal and operation before being shipped and is capable of bypassing up to 800HP worth of air! The Supersonic Bov5 is all about noise, flow and is 100% Vent to Atmosphere. These are more suitable on vehicle’s not equipped with Air Flow Meters and feature single large trumpet for maximum presence!
