Product Description

The **GFB T9110 Mach 2 TMS** diverter valve is an OEM-style upgrade designed for turbocharged 2.0L GDI platforms like Hyundai i30 N, Veloster N, Kia Stinger, Genesis G70, and related models. By replacing the factory bypass valve, it enhances throttle response and boost recovery while maintaining smooth recirculation--perfect for daily-driven turbo builds that demand reliability.

Equipped with GFB's TMS (Turbo Management System) technology, this valve aggressively holds boost and recovers pressure faster than the stock unit. Its pressure-balanced internal design ensures no boost leaks, even under extreme conditions. For those desiring a more aggressive "hiss," an optional atmosphere venting conversion kit is available. Backed by a lifetime warranty and robust stainless/aluminum construction, the T9110 is built to last in performance applications.
