TurboXS Racing Hybrid 50/50 BOV Kit - 02-07 WRX, 04-21 STI

Not too loud and not too quiet, the WS-HYB from TurboXS is the valve for you if you want an upgraded Blow Off Valve that you can hear when you want to but not when you don't. Utilizing our all new modular "XS" BOV platform, this valve is designed to vent partly to atmosphere and partly back to the intake giving you the best of both worlds. This valve comes complete with everything you need to replace your stock bypass valve.
