GFB Deceptor Pro II Electronic Blow Off Valve – Subaru WRX/STI (GC8) MY94-96 / Toyota Supra (JZA80) – 20mm

Application: Subaru WRX/STI (GC8) MY94-96 / Toyota Supra (JZA80)
Part Type: Deceptor Pro II Electronic Blow Off Valve – 20mm


GFB has taken its popular Response valve concept and added full electronic control over venting bias, letting you dial in the sound of your blow off valve from the driver's seat. The Deceptor Pro II uses a geared electric motor and precision ball bearing supported gear train to shift smoothly between a silent factory style hiss and a loud atmospheric vent, or anything in between, without pulling anything apart.

This listing covers the 20mm Deceptor Pro II for the Subaru WRX and Subaru STI (GC8) MY94-96, and the Toyota Supra (JZA80). The valve body is compact enough to suit most factory locations, though some vehicles will need minor hose modifications to mount it correctly.

Note: On the GC8 WRX and STI, hose modification may be required to relocate the valve elsewhere in the engine bay. On the JZA80 Supra, this is not a direct bolt on and will require modification to factory hoses to fit.


Key Features

  • Remote proportional venting control from silent to full atmospheric vent
  • Backlit in-car controller with adjustable end point for maximum vent bias
  • High-torque geared electric motor with sealed ball bearing supported gear train
  • Revised porting for improved flow and venting response
  • 20mm valve body, compact design for factory-location fitment
  • Supplied with wiring and hardware required for installation

Vehicle Fitment

  • Subaru WRX/STI (GC8) MY94-96
  • Toyota Supra (JZA80)

Please confirm your vehicle's year and engine configuration before ordering, as hose modifications may be needed.
