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. 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!. 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..
