Application: Ford Falcon XR6 Turbo (BA/BF/FG) / Territory Turbo (SY) / Audi TT/A3/S3 (8N/8L) / VW Golf GTI (Mk4)
Part Type: Respons Dual Port Variable Blow Off Valve – Bosch 25mm

GFB pioneered the dual port blow off valve back in 1999, and the Respons TMS takes it further with a patented venting bias adjuster that lets you dial in the exact blow off sound you want, without the stalling or fuelling issues that plague other atmo valves. It's a direct bolt-on replacement for the factory Bosch 25mm valve on the Ford Falcon XR6 Turbo and Territory Turbo.

This listing covers the Ford Falcon XR6 Turbo (BA/BF/FG), Territory Turbo (SY), Audi TT (8N), Audi A3/S3 (8L), and VW Golf GTI (Mk4) — all sharing the same Bosch 25mm valve body. SKU T9025.

Important: The GFB valve must be installed in the opposite orientation to the factory Bosch valve — air enters at the bottom and dumps through the sides.
