The Hybrid is Back!

Celebrating 20 Years of the World’s First Dual Outlet BOV

In 1998, GFB’s founder, John Adrian, frustrated with his WRX stalling due to an atmosphere-venting BOV, invented the Hybrid—the world’s first dual-port blow-off valve.

This game-changing design reduced stalling and backfiring while delivering the iconic blow-off sound. It became an industry standard, inspiring the Respons TMS and Deceptor Pro.

Now, to mark 20 years of innovation, GFB is bringing the Hybrid back! With updated features, including adjustable venting modes (recirc, atmo, or 50/50) and direct bolt-on kits, it’s time to own a piece of turbo history.
