TurboXS Hybrid BOV 2002-2007 WRX/2004-2021 STI

Love that blow-off-valve air-whooshing sound, but hate the compromises in driveability that come with a full atmospheric BOV? What to do? TurboXS offers their answer to that age-old conundrum.

The Hybrid BOV returns all its air to the intake, just like the stock bypass valve, at low throttle. Then at full throttle, it vents through atmospheric slots, giving that classic "Pssssshhht!" sound.

Like all TurboXS blow-off valves, the Hybrid BOV is machined from solid billet aluminum and brass, for unsurpassed durability and reliability.

Note that you will be re-using your stock bypass valve elbow; if you don't have that, you can order one a replacement HERE.

Fits all 2002-2007 WRX and 2004-2021 WRX STI.
