Turbosmart BOV5 Supersonic Blow Off Valve - Subaru WRX (GD/GG) / WRX STI (GD/GR/GV) / Forester XT (SG)
The Turbosmart Supersonic for Subaru is an easy-to-install, direct-fit BOV5 valve that vents fully to atmosphere, offering significant flow and a big sound for serious street and race builds. The Turbosmart BOV5 is a 38mm positive-seal piston valve built on Turbosmart's Boost-Balance design, so the more boost it sees the better it seals. It is machined from billet aluminium and hand assembled with a precision-matched piston, with every valve tested before dispatch.
Note: As a full vent-to-atmosphere valve, check with your tuner that it suits your airflow metering. A hose blanking plug and breather crossover hose are included. Installation by a professional is recommended.
