GFB Deceptor Pro II Electronic BOV - Ford Falcon XR6 Turbo (BA/BF/FG) / Audi TT/A3/S3 (8N/8L) / VW Golf GTI (Mk4) / Saab 9-3/9-5 - 25mm
GFB built the Deceptor Pro II for drivers who want full control over their BOV sound, not just a fixed valve. Instead of a single fixed venting bias, this unit lets you dial in anything from silent to full atmospheric blow off from a backlit in-cabin controller, so your Ford Falcon XR6 Turbo, Audi TT/A3/S3 or VW Golf GTI can sound exactly how you want it, on the fly.
This listing covers the 25mm Deceptor Pro II for Ford Falcon XR6 Turbo (BA/BF/FG), Ford Territory Turbo (SY), Mazda MX-5 Turbo (NB), Audi TT/A3/S3 (8N/8L), Audi A4 (B5/B6), Audi S4 (B5), VW Passat (B5), VW Golf GTI (Mk4), VW Polo (9N), VW Beetle (9C), VW Bora (1J) and Saab 9-3/9-5 Turbo models fitted with the 1.8T, 2.7TT or equivalent factory turbo setups.
Note: GFB valves must be installed in the opposite orientation to the factory plastic Bosch valve — air enters at the bottom and dumps through the sides. Audi S4 (B5) 2.7TT applications require two valves.
