Respons T9007 Diverter/Blow-Off Valve

The Go Fast Bits Respons T9007 is a high-performance diverter/blow-off valve engineered with an adjustable venting bias system for Subaru vehicles. This patented system, derived from GFB's Stealth FX technology, allows for fine-tuning the proportion of air vented to the atmosphere versus recirculated back into the intake. This capability directly controls the audible blow-off sound, offering a spectrum from completely silent factory operation to a loud, atmospheric release, or any setting in between. Beyond sound customization, the Respons T9007 enhances performance through GFB's Turbo Management System (TMS) principle. The balanced piston design also ensures unlimited boost holding capability, as boost pressure on both sides cancels out forces, preventing the valve from being forced open. This hybrid valve is designed as a direct bolt-on replacement, fitting into the factory location without requiring vehicle modifications. It is specifically suited for Subaru applications including the XT MY14-18 SJ (FA20 engine), WRX MY14-21 (FA20 engine), and Levorg FB16/FA20 turbo MY16-on. The valve features a piston design and comes in an Asphalt (61K) finish.
