GFB T9102 Diverter Valve

Improved performance for Mazda, Mitsubishi and Nissan cars

Go Fast Bits Mach 2 T9102 is designed to improve boost recovery by up to 30% faster than stock diverter valves.

The GFB Mach 2 is capable of holding unlimited boost whilst the innovative TMS technology guarantees maximum throttle response.

Easy to install, the GFB T9102 is manufactured to ISO 9001 standards whilst maintaining the factory solenoid from the stock diverter valve.

The plastic parts from the original stock blow off valve are replaced by indestructible metal from the Go Fast Bits T9102.

Full detailed instructions are simple to follow for easy installation.
