ALL THE PERFORMANCE WITH THE NOISE! The Hybrid valve is back! In 1999, GFB's first Hybrid valve pioneered the dual port design, which was so successful the technology has since been adopted by most other brands. By "staging" the two venting outlets, at low valve lifts most of the air is recirculated. As the car is driven harder, the valve opens further and more of the atmosphere venting port is exposed for a louder sound. As a benefit, this system makes it possible to use these valves on cars with sensitive airflow meters that often suffer issues such as backfiring and/or stalling, whilst still achieving the signature blow-off sound.

The Hybrid direct fit bolt-on range covers a huge list of popular vehicles. You can also purchase a variety of hose and flange adaptors for custom fitments. Please check the application guide on page 15 to find the Hybrid model for YOUR car!

GFB?s Hybrid Blow off/diverter valve is 3 Valves in one; the Hybrid is a dual outlet valve for combined recirc and atmosphere venting, this system makes it possible to be used on cars with sensitive airflow meters.

Want it loud? Quiet? In between? GFB Hybrid kits include a pair of blanking plugs that allow the valve to be configured for full recirculation venting, 50/50 (atmosphere / recirc), or full atmosphere venting.
