Deceptor Pro 2 In-Cabin Adjustable Bias Diverter – Kia/Hyundai 1.6T-GDI Smartstream (G4FP)
The latest Smartstream 1.6 T-GDi engines fitted to Hyundai’s 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.
This Deceptor Pro 2 TMS valve features dual-outlets with a full bias adjustment system that allows you to control the venting bias to your taste immediately and directly from the driver’s seat.
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.
