GFB Mach 2 TMS Recirculating Diverter Valves (Pair/2), 2009-2020 GT-R

The Mach 2 is available in a range of universal and bolt-on kits for most popular turbo models. And when we say "bolt-on", that's exactly what we mean! No additional adaptors, parts or vehicle modifications are required - simply remove the factory bypass valve and replace it with the Mach 2 - it's that simple!
The Mach 2 is configured as a 100% recirculating valve (i.e. bypass, plumb back) as a direct factory replacement, for when you want all the performance WITHOUT the noise!
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 to protect the engine and the other is they are not optimised for throttle response.

Included:
• GFB Mach 2 TMS Recirculating Diverter Valves (Pair/2), 2009-2020 GT-R

Features:
• The Mach 2 solves both issues. With its pressure-balanced design, the Mach 2 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.
