This patent-pending master kit from Quick Fuel Technology combines the superior fuel atomization of a carburetor with the precise fuel control of EFI, boasting an 8-hole venturi sleeve with annular discharge booster to provide superior fuel atomization where air speed is highest and pressure is lowest. The result?  A faster and more efficient burn, more power, and better response. Fuel is also supplied below the throttle plates for increased stability and idle control.

The QFI-500BDM Master Kit includes TBI assembly, handheld controller, ECU, main wiring harness, fuel pump, fuel filter, fuel line, laptop cable, sensors, and hardware.
