Nissan R35 GTR Skyline Blow Off Valve/BOV  ( 2 Valve set)  Go Fast Bits / GFB T9202 Respons TMS BOV

The GFB TMS Respons is the best BOV on the market. This is the only Blow Off Valve to consider for your R35 GTR Nissan Skyline. The GFB T9202 Respons offers a campact design and features found on no other BOV in the WORLD, better throttle response, less tubro lag and GFB's  fully Patanted quick and easy venting bias adjustment system.

The ability to change the sound of a blow-off valve is increasingly becoming an important issue with buyers, who want to sound different from everyone else.

GFB have released the Whistling Trumpet (part # 5701), which emitted a piercing screech when driving aggressively. Unfortunately for a number of GFB owners, the 5701 trumpet only worked with some valve types.

For the owners of all other types of GFB valves, GFB have now released the 5702 – a modified version of the Whistling Trumpet that is designed to work on low boost applications where the 5701 doesn’t cut it. 

The 5702 can be used in place of the standard trumpet on all GFB valves, and will make the whistling sound more readily than the 5701 (high boost and RPM is required to get the whistle from a 5701), and at a slightly higher pitch.  Like the 5701 however, it is necessary to run the valve so that all (or most) of the air vents through the trumpet – Respons valves will typically not generate the velocity required to whistle when set to 50/50 venting.

5701 Recommended for Part numbers T9003 & T9503

5702 This part is recommended for Respons and Deceptor Pro II valves EXCLUDING T9003 & T9503
