GFB Deceptor Pro II Electronic Blow Off Valve - Universal
GFB built its reputation on smart, adjustable blow off valves, and the Deceptor Pro II takes that further with electronic control over your venting bias, right from the driver's seat. It's a proven option for anyone running a custom turbo setup who wants full command over BOV sound without swapping hardware.
This listing covers the T9519 v-band version of the Deceptor Pro II, built for direct weld-on mounting to aluminium or stainless steel intercooler piping. It suits custom builds where a bolt-on flange isn't an option, and pairs with GFB's range of v-band flanges and outlet fittings sold separately.
Note: This kit does not include the weld-on v-band flange or outlet fitting. These are sold separately in various materials and outlet sizes to suit your piping.
Key Features
- Electronic, on-the-fly adjustment of venting bias from inside the cabin
- Backlit in-car controller with smooth volume dial
- Revised internal porting for improved flow and response
- High-torque geared motor with sealed ball-bearing gear train
- End point adjustment to set maximum atmosphere venting

Vehicle compatibility, mounting flange options, and outlet sizing are detailed in the tabs above. Please confirm your piping diameter and material before ordering the matching flange and outlet fitting.
