WRX Blow Off Valves Let's See What We Have Here
Subaru WRX Blow off Valve Kits will allow you to hear more of a "whooshing" noise when you let off the throttle. Subaru's usually run best on the factory valve. Fully Atmospheric valves will be the loudest, whereas recalculating valves will give a smoother throttle response.
