DV+ solutions are production year dependent. Select accordingly.


  • Uses factory solenoid coil for seamless integration
  • Replaces plastic valve parts with metal for reliability and strength on chipped engines
  • Direct-fit replacement with TMS benefits
  • Exclusive “pilot-actuated” valve mechanism for rapid response at high boost
  • The T9353 is designed to fit in the tight confines of the Mini N18 engine bay. The T9353 kit splits the DV+ into two parts, the valve, and the solenoid, (which are joined by hoses), meaning the solenoid can be mounted lower in the engine bay out of the way.
  • Other manufacturers’ products involve replacing the entire system with a traditional pneumatic valve. (i.e. no electronic control). This approach is really a step backwards in technology (a bit like replacing fuel injection with a carburettor) resulting in slower response and effectively removing any control the ECU has over the valve operation.
  • This DV+ solution on the other hand is more responsive, offers better boost recovery on gearshift, retains ECU control and doesn’t cause compressor surge/ turbo flutter. Oh, and it doesn’t require different springs or frequent rebuilds either. It’s just the way the factory diverter valve SHOULD BE!
