    Manufacturer's Part Number:

    FAST's EZ-EFI Self-Tuning Fuel Injection Kits are the worlds simplest fuel injection system on the market today. Designed for all applications making up to 650 horsepower, the EZ-EFI Fuel System easily bolts onto any carbureted or multi-port application in a single afternoon, making it the easiest EFI system you will ever install. Simply hook up the system, answer the questions from the improved Setup Wizard on the color touchscreen hand-held unit, and the system will tune itself as you drive.

    The FAST EZ-EFI features a die cast and black powder-coated four injector throttle body with integrated fuel rails. It provides even fuel distribution and adequate airflow, no replacement is needed. In addition to matching any 4150-style carbureted manifold, the EZ-EFI Self-Tuning Fuel Injection System also works with your original carb-style throttle linkage and features OEM sensors, including standard GM versions. It also works with all ignition setups, including HEI.

    The included hand-held device offers a variety of display dashes, a clean and easy to use interface and an LED indicator that can alert users to errors (including overheating) or be used as a shift light. The wiring harness features a premium loom, added protective fuses and a streamlined design, while the ECU hardware provides added protection against electrical/ignition noise and hardware damage.


    • No tuning experience or laptop needed; intuitive Setup Wizard guides you through the start-up process & the system tunes itself.
    • 4150 throttle body works with original carb-style linkage & uses all OEM sensors.
    • Works with any ignition setup, including HEI.
    • Built-in diagnostics & “limp mode” provide maximum engine protection in the event of trouble.
    • Made in the USA.
