GFB Mach 2 TMS Recirculating Diverter Valve for Select Subaru 2001-2020 (T9103)
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits select 2001-2020 Subaru Impreza, WRX, STI, and Forester models. The GFB Mach 2 TMS Recirculating Diverter Valve is a direct-replacement performance upgrade for factory valves that often leak or fail under high boost. Using GFB's proprietary Turbo Management System (TMS) technology, this valve is engineered to improve throttle response and ensure rapid boost recovery during gear shifts.
Unlike atmospheric valves that vent to the air, the Mach 2 is a fully recirculating unit that keeps the engine management system happy by returning air to the intake. It features a heavy-duty brass piston and precision-machined housing capable of withstanding boost pressures in excess of 100 psi, making it suitable for everything from stock daily drivers to high-horsepower builds.
- Manufacturer Part Number: T9103
- TMS Technology for faster boost recovery and sharper throttle response
- Full recirculating operation for quiet, factory-style performance
- Tested to withstand boost pressures of 100+ psi
- Direct bolt-on fitment for Subaru factory mounting points
- Includes all necessary hardware for installation
