GFB Mach 2 T9112: Recirculating Diverter Valve Kit for Kia Stinger / Genesis G70 3.3T

Want better turbo response without the loud blow-off sound? The GFB Mach 2 T9112 is a 100% recirculating (plumb-back) diverter valve kit that keeps things quiet while improving performance.

Using GFB’s TMS (Turbo Management System) principles, the Mach 2 can help the engine return to peak boost faster during throttle modulation, improving drivability and response.

The T9112 kit is a true direct bolt-on for the Kia Stinger V6 twin turbo setup — no extra adaptors, parts, or vehicle modifications required. Remove the factory bypass valves and install the Mach 2 valves in their place.

• 100% recirculating design for stealthy performance (no “whoosh”)
• Improves boost holding vs factory bypass valves
• Sharper throttle response and quicker boost recovery during throttle changes
• Direct bolt-on kit designed for the factory valve locations
