The GFB Mach 2 TMS Recirculating Diverter Valve is engineered as a direct replacement for the factory bypass valve fitted to selected Hyundai, Kia, and Genesis 2.0T-GDi turbocharged vehicles. It delivers measurable performance gains without introducing blow-off noise.

TMS Technology for Faster Boost Recovery

At the heart of the Mach 2 valve is GFB’s patented Turbo Management System (TMS). This allows the valve to respond progressively to boost pressure, helping the turbocharger return to peak boost more quickly during gear shifts and throttle modulation.

Quiet OEM-Style Recirculation

By fully recirculating excess boost back into the intake system, the Mach 2 maintains factory airflow behaviour. This ensures smooth drivability and compatibility with mass airflow (MAF) based engine management systems.

True Direct-Fit Design

The Mach 2 is designed as a bolt-on replacement using factory mounting points and connections. No adapters, fabrication, or tuning changes are required for installation.

Built for Long-Term Reliability

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