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 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.

  • Dual staged venting outlets, configurable for full recirculation, 50/50, or full atmosphere operation using the provided plugs. TMS technology enables up to 30% faster boost recovery on gearshift

The Go Fast Bits GFB Hybrid TMS Dual Port Blow-Off Valve is engineered to enhance your Subaru's performance with innovative venting technology. Featuring a dual staged venting system, this valve allows you to configure full recirculation, split operation, or full atmosphere venting by simply swapping out provided plugs, making it adaptable to a variety of driving preferences and airflow meter sensitivities. Its design leverages the original hybrid venting concept introduced in 1999, which has since been adopted across many brands for its proven efficiency and sound characteristics. The venting outlets are staged to recirculate most of the air at low valve lifts, reducing turbo lag and maintaining smooth boost response, while at higher lifts, the valve opens wider for a louder sound and more atmosphere venting to produce an aggressive exhaust note. This feature is particularly beneficial for enthusiasts seeking improved throttle response and auditory feedback during spirited driving. The GFB Hybrid TMS Valve also incorporates TMS technology, which provides up to 30% faster boost recovery after gear shifts, contributing to quicker spool times and enhanced acceleration. Designed specifically for Subaru models including the Impreza, WRX, and Forester XT from 2004 to 2008, this valve offers an easy bolt-on upgrade that maintains compatibility with sensitive airflow meters. Its robust construction ensures durability under demanding conditions, and its adjustable venting options make it a versatile tool for tuning your vehicle’s turbo system. Note that this product is not CARB approved and requires carb acknowledgment, making it suitable for off-road or racing applications where emissions compliance is not mandated. Whether you're aiming for improved performance, a more aggressive sound, or faster boost response, the GFB Hybrid TMS Dual Port Valve offers a reliable and adaptable solution for your Subaru turbocharged engine.

  • Dual staged venting outlets: configurable for full recirculation, split, or full atmosphere venting with provided plugs.
