Product Description

The Go Fast Bits T9111 Mach 2 Recirculating Diverter Valve is engineered to improve throttle response and boost recovery on turbocharged Hyundai and Kia models equipped with the 1.6L T-GDI engine. Using GFB's Turbo Management System (TMS) technology, the valve offers up to 30% faster boost recovery between shifts for a smoother, more responsive driving experience.

Designed as a direct bolt-on replacement for the OEM diverter valve, the T9111 features a pressure-balanced piston design capable of handling over 100 psi. Its 100% recirculating configuration makes it ideal for daily-driven vehicles by maintaining quiet operation and factory emissions behavior. For enthusiasts who prefer a more aggressive sound, an atmospheric conversion kit is available separately.
