The stock diverter valve is a common source of problems and power loss in N20 powered BMWs.

By upgrading your diverter valve while retaining the stock solenoid with this GFB direct-fit diverter valve, you can experience sharper throttle response, faster valve actuation, and will not give up under higher boost loads!


  • Retains the factory solenoid coil for seamless integration
  • Replaces plastic valve parts with metal for reliability and strength on chipped engines
  • Direct-fit replacement with GFB’s TMS benefits
  • Exclusive “pilot-actuated” valve mechanism for rapid response at high boost
