Hyundai i30/Kia Cerato Blow Off Valve - GFB Recirculate

Hyundai i30 1.6L and Kia Cerato 1.6L Blow Off Valve/Diverter
GFB MACH 2 Recirculate (no vent noise)
 
THE SIMPLE & ESSENTIAL MOD FOR 30% QUICKER BOOST
Utilising Proven TMS Technology To Ensure Dependable Boost Holding And Optimum Throttle Response
If you don’t need the patented venting bias adjustment feature of the Respons or Deceptor Pro, the Mach 2 is the answer.
Using GFB’s TMS technology the Mach 2 can help return the engine to peak boost up to 30% faster than a factory diverter valve when shifting gears (more information below).
Recirculation model for direct factory replacement for performance without the noise
Atmosphere venting kits to convert the recirculating valve if you want noise with your performance
 
The Mach 2 is configured as a 100% recirculating valve (i.e. bypass, plumb back) and add on kits are also available to convert to 100% atmosphere venting. Use the recirc model for direct factory replacement when you want the performance WITHOUT the noise! Add the conversion kit when you want some noise with your performance!
Factory bypass valves have two main shortcomings – one is that they are typically designed to blow open above a certain boost pressure to protect the engine, and the other is they are not optimised for throttle response.
The Mach 2 solves all of these issues. It can effectively hold unlimited boost (unlimited in that no turbo could ever produce enough pressure to damage it), and the TMS technology ensures maximum throttle response.
