Holley EFI - 550-501

HP EFI Universal Retrofit Multi-Point Fuel Injection Kit; For 4500 Carb Style Intake Manifold; Incl. Injector Bungs/Fuel Rails/Wiring/ECU/Sensors/Throttle Body;

Do you have a Mopar, Ford or other type engine you want to install multi-port fuel injection on? No, problem, the Holley HP universal MPI retrofit EFI kits are designed to be used with any V-8 intake manifold. The kit comes with injector bungs and un-machined fuel rails so you can modify to fit any single plane 4bbl intake manifold. The HP universal retrofit kits also come with the necessary wiring, ECU, sensors and throttle body. Just select the fuel pump and injectors of choice and you are off and running.
