Quick Fuel Injection - Combines the superior fuel atomization of a carburetor with the precise fuel control of EFI. Unique patent pending 8-hole venturi sleeve with annular discharge booster design provides superior fuel atomization at the ideal spot, where air speed is at its peak and pressure is at its lowest, atomizing fuel better than traditional injector nozzles. The result is faster and more efficient burn, more power, and better response. Fuel is also supplied below throttle plates for increased stability and idle control. Master Kit includes TBI Assembly, Handheld Controller, ECU, Main Wiring Harness, Fuel Pump, Fuel Filter, Fuel Line, Laptop Cable, Sensors & Hardware.
