The GFB T9101 Mach 2 TMS Recirculating Diverter Valve is engineered to enhance the performance of your turbocharged Subaru. Utilizing GFB's TMS (Turbo Management System) technology, this valve helps return the engine to peak boost up to 30% faster than the factory diverter valve during gear shifts, improving throttle response and overall drivability.

Designed as a direct bolt-on replacement, the T9101 requires no additional parts or modifications. Its 100% recirculating design ensures performance gains without the added noise associated with vent-to-atmosphere blow-off valves. The pressure-balanced piston design effectively holds unlimited boost, making it suitable for both stock and modified vehicles.

Constructed from billet aluminum and finished with black anodizing, the T9101 offers durability and corrosion resistance. The adjustable spring pre-load allows fine-tuning to match your driving preferences.
