TurboXS 50/50 Racing Bypass Valve Subaru 2002-2007 WRX / 2004-2019 STI

The TurboXS Hybrid 50/50 blow off valve is designed for those that want that great blow off sound without out the potential issues of going with a fully venting unit. Each time the throttle plate closes this valve will recirculate half of the boost while treating you and anyone within earshot to that trademark turbo sound. Included with the kit are a gasket, washers to increase spring tension, and necessary hoses.
