Hybrid T9225 Dual Outlet Diverter / Blow Off Valve for SAAB, Audi, VW, Ford.

GFB Hybrid Blow-Off Valve – 20th Anniversary Edition

GFB’s Hybrid Blow-Off Valve is back — celebrating 20 years since it first pioneered dual-port venting technology.

Originally developed to solve issues like stalling and backfiring in vehicles with MAF sensors, the Hybrid features a unique staged dual-port system. It opens the recirculation port first for smooth low-speed operation, while the atmospheric vent provides the signature blow-off sound under higher boost conditions.

This design quickly became a benchmark in the turbo world, influencing nearly every major BOV brand. Now, after years of innovation and success with models like the Respons TMS and Deceptor Pro, the Hybrid returns with modern updates and enhanced versatility.

The new Hybrid allows full recirculation, full atmospheric, or 50/50 venting, with a wide range of direct bolt-on kits available for popular vehicles. It’s an affordable, performance-driven solution that combines drivability with sound — ideal for enthusiasts who want the best of both worlds.

Awarded a Global Media Award at the 2017 SEMA Show, the Hybrid is more than a blow-off valve — it’s a piece of performance history
