GFB T9386 DV+ replaces the complete factory diverter valve on compatible BMW N13, N20 and N55 applications. Its integrated solenoid eliminates reuse of the original coil, and the compact housing helps in tight installations.
Key Features
- Progressive pilot-operated valve action helps smooth throttle transitions.
- Designed to improve boost retention and recovery after a brief throttle lift.
- Recirculates air while retaining ECU control.
- Low-profile solenoid replaces the aging factory coil.
