GFB Mach 2 TMS Recirculating Valve for Kia Smartstream G4FP engines

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 drivability issues or 'Check Engine' lights.

However, this Mach 2 valve is for those who want all the performance of the GFB TMS valve technology without any of the noise.

That said, Mach 2 gives you the freedom to fit an optional Atmospheric Venting Conversion kit at a later date to give you all the sound so you don't need to buy a new valve.

All the Performance With or Without the Noise!

GFBÕs Mach 2 utilises GFBÕs proven TMS Technology to ensure rapid boost recovery on gearshift and optimum throttle response, as well as the ability to withstand boost pressures of 100psi+. Put simply, it can hold more boost than any turbo could produce.

With its single venting outlet, the Mach 2 is configured from the factory for full recirculation (i.e. plumb back, diverter, bypass) venting for the performance-minded who just want the benefits without the sound.

• Single venting outlet, factory configured for full recirculating operation
• Configure for full atmosphere venting with separate atmosphere conversion kit
• TMS Technology for up to 30% faster boost recovery on gearshift
• Huge range of direct bolt-on kits
• 100psi+ boost holding ability
• Manufactured in Australia in accordance with ISO 9001
