GFB Mach 2 Recirculating Plumb Back Blow Off Valve - Subaru WRX (VA) / Forester XT (SJ) / Levorg (VM)

The GFB Mach 2 is a recirculating blow off valve for the Subaru WRX (VA, 2015-2021), Forester XT (SJ, 2013-2018) and Levorg (VM, 2014-2021). GFB's TMS technology restores boost up to 30 percent faster than the factory diverter valve on gear shifts, improving throttle response and boost holding. It is a direct bolt-on replacement for the factory bypass valve, with no cutting, adaptors or tuning changes needed. The valve keeps the factory's quiet recirculating operation, and atmosphere conversion kits are sold separately for an audible blow off.
