Mach II Diverter Valve and atmo option for the performance-minded Subaru WRX MY01-07, STi MY02-on, XT Forester MY05-08

Why?

ALL THE PERFORMANCE WITH OR WITHOUT THE NOISE!, GFB's Mach 2 utilises GFB's proven TMS Technology to ensure rapid boost recovery on gearshift and optimum throttle response, as well as the ability to withstand boost pressures of 100psi+. Put simply, it can hold more boost than any turbo could produce

With its single venting outlet, the Mach 2 is configured from the factory for full recirculation (i.e. plumb back, diverter, bypass) venting for the performance-minded who just want the benefits without the sound.

The Mach 2 direct fit bolt-on range covers a huge list of popular vehicles. You can also purchase a variety of hose and flange adaptors for custom fitments. Please check the application guide to find the Mach 2 model for YOUR car!,

Holds air

Works great! It wven has a hint of BOV sound. STI did not run right with non-recirculating BOV. Works great with this one. Great price and it will hold a lot more boost than stock.
