The GFB GT Hybrid is a model-specific BOV that comes as a complete kit that is very simple and quick to install. Absolutely no vehicle modifications are required, and as with all GFB Hybrid valves, the kit comes with a plug set to allow three venting configurations:

100% plumb back for silent operation, just like the factory valve
100% atmosphere for maximum noise
50/50 plumb back/atmosphere for a more subtle but audible blow-off sound
With its three-step sound adjusmtent capability, the GT Hybrid is the perfect more affordable alternative to the Stealth FX and Deceptor Pro models.


The GT Hybrid is available in 3 versions:


Part # 1015 (only available in black)
