GFB Mach 2 Blow Off Valve – Subaru WRX (GH/GR) / Liberty GT (BL/BP) / Forester XT (SH) – Recirculating

Application: Subaru WRX (GH/GR) / Liberty GT (BL/BP) / Forester XT (SH)
Part Type: Mach 2 Blow Off Valve – Recirculating

GFB has built a solid reputation on TMS technology, and the Mach 2 is a straightforward way to get a genuine boost response upgrade without fuss. Designed as a direct bolt-on replacement, it suits the Subaru WRX, Liberty GT and Forester XT without any extra adaptors or vehicle modifications required.

This listing covers the 2008-2014 WRX, 2004-2009 Liberty GT and 2008-2013 Forester XT. It's configured as a 100% recirculating (plumb back) valve for factory-style performance without added noise, keeping things quiet and OEM-like under the bonnet.

Note: This is the recirculating version. If you want atmosphere venting sound, you'll need GFB's separate Atmosphere Conversion Kit or a hose plug and trumpet outlet, sold separately.
