GFB Mach 2 TMS Recirculating Diverter Valve - 25mm (1997-2009 Audi, VW, Saab) (1.8T / 2.3T)
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits select 1997-2009 Audi A4 and TT, Saab 9-3 and 9-5, and Volkswagen Beetle, Golf, and Passat models (1.8T / 2.3T).
The GFB Mach 2 TMS Recirculating Diverter Valve is a performance-oriented replacement for weak factory plastic or diaphragm-style valves. Utilizing GFB’s Turbo Management System (TMS) technology, this valve is engineered to reduce turbo lag by keeping the turbine spinning during gear shifts, ensuring rapid boost recovery and sharpened throttle response. Unlike OE valves that can leak or fail under increased load, the Mach 2 is proven to withstand boost pressures in excess of 100 psi.
- Direct replacement for factory 25mm diverter valves (MPN: T9125)
- TMS Technology for faster boost return on gearshift
- Tested to hold 100+ psi without leaking
- Recirculating operation maintains factory-style airflow management
- Precision-machined internal components for maximum durability
- Includes 25mm inlet and 25mm outlet ports
