Precision Boost Management for 25mm Systems

The Go Fast Bits (GFB) Mach 2 TMS Recirculating Diverter Valve is the gold standard for 25mm inlet/outlet turbo systems. Designed to replace weak factory diverter valves, this unit utilizes GFB's renowned Turbo Management System (TMS) technology to provide rapid boost recovery and razor-sharp throttle response.

Why Choose the GFB Mach 2?

  • Versatile Fitment: Designed for a wide range of vehicles including classic Audi A4, VW Golf, Passat, and Saab 9-3/9-5 models.
  • Bulletproof Construction: Capable of handling over 100psi of boost, making it the last diverter valve you will ever need to buy.
  • Recirculating Design: Maintains factory-style operation, ensuring your engine management system remains perfectly calibrated while improving performance.
  • Enhanced Throttle Response: Reduces lag by ensuring the valve closes instantly after a shift, keeping the turbo spooled and ready.

This valve is the ideal solution for enthusiasts looking to maintain a stealthy, factory-like sound while enjoying the performance benefits of a high-end aftermarket upgrade. Its robust internal design prevents the common failures associated with plastic OEM valves, such as diaphragm tearing or boost leaks. When you need reliable performance parts that stand the test of time, look no further than the selection at GGCRACING.
