GFB Mach 2 Recirculating Blow Off Valve – Subaru WRX/STI (GC8) MY94-96 / Toyota Supra (JZA80) – 20mm

Application: Subaru WRX/STI (GC8) MY94-96 / Toyota Supra (JZA80)
Part Type: Mach 2 Recirculating Blow Off Valve – 20mm

GFB's Mach 2 uses proven TMS technology to restore boost up to 30% faster than a factory diverter valve, giving you sharper throttle response without the compromises of the stock bypass valve. It's a straightforward, no-fuss upgrade for anyone wanting better response without adding noise. SKU T9120.

This listing covers the 20mm Mach 2 recirculating valve for the Subaru WRX and STI (GC8) MY94-96, and the Toyota Supra (JZA80). The valve ships as a 100% plumb back unit for factory-style performance, with atmosphere venting conversion kits available separately if you want some noise with your boost.

Note: Fitment on the WRX and STI may require modification to factory hoses to relocate the valve elsewhere in the engine bay. On the Supra JZA80 this is not a direct bolt-on and will require hose modification to install.
