Go Fast Bits Respons TMS Hybrid Blow-Off Valve

The Go Fast Bits T9001 Respons TMS is a hybrid blow-off valve engineered for performance enhancement, specifically targeting turbo lag reduction and improved throttle response. It integrates GFB's patented adjustable bias venting system, offering a unique capability to control the proportion of air vented to the atmosphere versus recirculated back into the intake. This feature allows users to customize the blow-off sound from silent operation to maximum noise, or anywhere in between, without compromising the vehicle's drivability. Constructed with an aluminum body, this direct-fit valve ensures a seamless installation into the factory location without requiring additional adapters or vehicle modifications. The T9001 utilizes GFB's Turbo Management System (TMS) principle, which differs from factory bypass valves by remaining shut until required to open. Furthermore, the valve's balanced piston design guarantees unlimited boost-holding capability, as it cannot be forced open by high boost pressure. This GFB Respons TMS valve is specifically designed for the 2008-2014 Subaru WRX and the 2005-2009 Subaru Legacy GT.
