Turbo XS 2015 Subaru WRX Hybrid BOV Blow Off Valve Type XS - W15-XS-HYB

Not too loud and not too quiet, the W15-XS-HYB is the valve for you if you want an upgraded Blow Off Valve you can hear when you want to but not when you don't. Designed specifically for the 2015 WRX using our XS BOV platform, this valve vents partly to atmosphere and partly back to the intake giving you the best of both worlds. The modular XS platform design allows you to change both the inlet and the outlet yourself, letting you convert from 50/50 Hybrid to 100% Vent to Atmosphere with optional purchased parts.
