Mach 2 TMS Recirculating Diverter Valve for Hyundai & Kia 1.6T-GDI

The GFB Mach 2 T9111 is designed as a direct replacement for the factory bypass valve fitted to Hyundai and Kia vehicles running the Gamma 1.6T-GDI engine. By retaining full recirculation, it delivers improved performance without introducing atmospheric blow-off noise.

TMS Technology for Faster Boost Recovery

At the core of the Mach 2 is GFB’s patented TMS (Turbo Management System) technology. This allows the valve to respond progressively to changes in boost pressure, helping the turbo return to peak boost faster during gear changes and throttle modulation.

Quiet, Fully Recirculating Operation

Unlike atmospheric blow-off valves, the Mach 2 T9111 recirculates excess boost back into the intake system. This preserves factory airflow behaviour and ensures smooth drivability on MAF-based engine management systems.

Direct-Fit, No Tuning Required

The T9111 is engineered as a true bolt-on replacement for the factory diverter valve. No additional adapters, hoses, or tuning changes are required, making it a straightforward performance upgrade.

Built for Reliability

Precision-machined internal components provide consistent sealing under boost and long-term durability, even on vehicles running increased boost pressure.
