GFB Mach 2 T9103 TMS Recirculating Diverter Valve – Subaru WRX & STI
Mach 2 T9103 TMS Recirculating Diverter Valve for Subaru Turbo Models
If you want performance without the noise, the GFB Mach 2 is configured as a 100% recirculating (plumb-back) diverter valve. The T9103 is a direct-fit replacement for the factory bypass valve on selected Subaru turbo applications, delivering sharper response and quicker boost recovery with sleeper-quiet operation.
TMS Technology for Faster Boost Recovery
GFB’s Turbo Management System (TMS) concept is designed to help the turbo return to boost more quickly after gear changes and during brief throttle lifts. The result is a more responsive feel in real driving conditions, especially when you’re modulating the throttle.
Boost Holding and Smooth Driveability
Factory bypass valves can include compromises that impact boost holding and throttle response. The Mach 2 is engineered with a pressure-balanced design to help hold boost reliably while maintaining consistent, predictable operation.
True Direct-Fit Installation
This is a bolt-on solution: remove the factory bypass valve and replace it with the Mach 2. No additional adaptors, parts, or vehicle modifications are required.
