GFB Hybrid Dual Port BOV – Subaru WRX/STI (GC8) MY94-96 / Toyota Supra (JZA80) / Ford Laser/TX3 (BF/BG) – 20mm

Application: Subaru WRX/STI (GC8) MY94–96 | Toyota Supra (JZA80) | Ford Laser/TX3 (BF/BG)
Part Type: Dual Port Blow Off Valve (BOV) – 20mm

GFB's Hybrid was the world's first dual port blow off valve, invented back in 1998 to stop early turbo cars stalling on their factory MAF sensors. The staged venting design opens the recirculation port before the atmosphere port, giving a smooth transition into that classic blow off sound without upsetting idle. Now back in production, it's a solid fit for the Subaru WRX/STI, Toyota Supra and Ford Laser/TX3 platforms covered here.

This listing covers the 20mm GFB Hybrid dual port BOV for the Subaru WRX and STI (GC8) MY94-96, Toyota Supra (JZA80), and Ford Laser/TX3 (BF/BG). The valve can be configured for full recirculation, full atmosphere, or a 50/50 split to suit your preference and local noise requirements.

Note: Fitment to the GC8 WRX/STI and JZA80 Supra is not a direct bolt-on — factory hoses will need modification to relocate the valve elsewhere in the engine bay.
