Experience Superior Boost Response with GFB Hybrid TMS

The Go Fast Bits (GFB) Hybrid TMS Blow Off Valve is the gold standard for turbocharged Subaru performance. Originally pioneering the dual-port design in 1999, this valve offers the perfect balance between recirculating air for smooth idle and venting to the atmosphere for that iconic blow-off sound. By staging the venting outlets, the valve ensures your engine maintains optimal air-fuel ratios during low-load driving while delivering an aggressive audible signature under heavy boost.

Key Features and Benefits:

• Dual-Port Technology: Recirculates air at low valve lifts and vents to the atmosphere at high lifts.
• Improved Throttle Response: Minimizes boost drop-off between shifts for consistent power delivery.
• Direct Fitment: Engineered specifically for 2005-2009 Subaru Legacy GT, 2008-2014 WRX, and 2008-2013 Forester XT models.
• Durable Construction: Precision-machined for longevity and reliable operation under high-boost conditions.

Whether you are daily driving or hitting the track, this valve prevents the common issues associated with full-atmosphere venting while giving your vehicle the performance edge it deserves. Installation is straightforward, allowing you to get back on the road with improved turbo efficiency. Trust GGCRACING for all your high-performance forced induction upgrades.
