GFB Deceptor Pro II Electronic BOV Blow Off Valve
GFB has built a reputation on getting BOV response right, and the Deceptor Pro II takes that further by putting the volume control in your hands, literally. Fitted to your Subaru WRX or STI, this electronic blow off valve lets you dial in venting bias from inside the cabin, from near silent to full atmospheric blow off, using a backlit remote controller.
This listing covers the 2001-2007 WRX, 2001-2007 STI, 2008-2014 STI, 2015-2021 STI, and 2006-2008 Forester XT. The compact housing is designed to bolt straight into most factory valve locations without major modification.
Important: Forester XT fitment is limited to triangle flange BOV setups only. If your Forester XT has a diamond flange, you'll need the GFB T9500 instead — check your factory flange before ordering.
Key Features
- Electronic, remote adjustable venting bias from silent to full atmospheric blow off
- Backlit in-car controller with proportional volume dial
- End point adjustment sets the maximum vent to atmosphere setting
- High torque geared electric motor with sealed ball bearing gear train
- Revised internal porting for improved flow

Vehicle compatibility, OEM part numbers, and fitment notes are provided in the tabs above. Please confirm your Subaru's model year and factory BOV flange type before ordering.
