Go Fast Bits Blow-off Valve Hybrid (35mm inlet - 30mm outlet - 30mm hose plug)
|
GFB pioneered the Hybrid system back in 1998 (which has since been copied by many other manufacturers), and has now added a new dimension!
The Hybrid is now an incredible 4 valves in 1! Featuring two venting outlets, the kit comes with two trumpets, a recirc outlet, a hose plug and an outlet plug. Using these parts you can set your Hybrid up for full recirc, 50/50, or full atmo (1 or 2 trumpets!), making it the most affordable noise-adjustable valve on the market.
When in 50/50 venting mode, half of the vented air is recirculated, which results in a slightly more subdued blow-off noise. It also means that certain Audi/VW, Nissan, Mitsubishi and other cars with sensitive airflow meters can use this valve and make a great blow-off sound without backfiring or ECU error codes. No other manufacturer can boast such success with these types of cars.
Of course, full recirc mode gives you silent operation just like the factory valve, and full atmo gives you maximum noise!
