Application: Subaru WRX (VA) / Forester XT (SJ) / Levorg (VM)
Part Type: Mach 2 Recirculating Plumb Back Blow Off Valve


GFB's Mach 2 uses proven TMS technology to bring your factory diverter valve up to speed, restoring boost up to 30% faster on gear shifts than the standard unit. Fitted to the Subaru WRX, Forester XT and Levorg, it's a genuine bolt-on replacement that improves throttle response and boost holding without any cutting, adaptors or tuning changes required.

This listing covers the Subaru WRX VA (2015-2021), Forester XT SJ (2013-2018) and Levorg VM (2014-2021). SKU T9107 is configured as a 100% recirculating (plumb back) valve, keeping factory quiet operation while improving performance. Atmosphere venting conversion kits are sold separately if you want an audible blow off sound.
