GFB Hybrid TMS Dual-Outlet Valve Kia/Hyundai 1.6T-GDI Smartstream (G4FP)
The latest Smartstream 1.6 T-GDi engines fitted to Hyundais i20 N and other models do not use a MAF sensor which means that you can vent to atmosphere for that blow-off sound, if you like, without causing any driveability issues or Check Engine lights.
The Hybrid TMS features dual outlets for full recirculation, 50/50, or full atmosphere venting. Configured with the supplied plugs for 3-stage sound control.
Product Note: Only for models with Smartstream 1.6T-GDI engine (G4FP), NOT Gamma 1.6T-GDI (G4FJ). You can identify Smartstream models because they will have Smartstream on the engine cover.
Why replace the factory bypass valve? Better performance! Factory bypass valves typically have two main shortcomings one is that they are often designed to blow open above a certain pressure, and the other is they are not optimised for throttle response.
