GFB Hybrid Dual Port BOV Ford Falcon XR6T (BA/BF/FG) / Audi TT (8N) A3 (8L) A4 (B5/B6) / Volkswagen Golf GTI (Mk4) 25mm

GFB Hybrid Dual Port BOV Blow Off Valve 25mm Audi/VW/Ford XR6T (Bosch Replacement)

GFB invented the dual port blow off valve back in 1998, and the Hybrid is the valve that started it all. This 25mm Bosch replacement stages its recirc and atmo ports so you get clean, reliable venting with the classic GFB sound, all in a compact bolt-on unit built for turbo platforms that ran the factory Bosch BOV.

This listing covers the Ford Falcon XR6 Turbo BA/BF and FG, Ford Territory Turbo SY, Mazda MX-5 NB (1.6T), and the Audi/VW 1.8T family including Audi TT 8N, A3 8L, S3 8L, A4 B5, A4 B6, VW Passat B5, Golf GTI Mk4, Polo 9N, Beetle 9C and Bora 1J, plus Audi S4 B5 (2.7 twin turbo) and Saab 9-3 and 9-5 Turbo models.

Important: The GFB valve mounts in the opposite orientation to the factory plastic Bosch valve — air must enter at the bottom and dump through the sides. The Audi S4 B5 twin turbo application requires two valves.
