The original EZ-EFI® 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 basic Setup Wizard questions on the hand-held unit, and the system will tune itself as you drive. That’s all it takes! And with our industry leading, in-house engineering team, you can rest assured that your investment is backed by a company that will be here after the sale.
Regardless of the make or size, this system easily bolts on easily to any carbureted engine making up to 650 HP – NO manifold 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 available at any auto parts store. What’s more, EZ-EFI® works with all ignition setups – including HEI. The EZ-EFI® can be installed easily in an afternoon and is a “must have” for your street rod or muscle car.
For more aggressive applications, the EZ-EFI® Dual Quad Upgrade Kit is capable of supporting 1200 horsepower engines with dual quad carburetor-type manifolds. In addition, the Multi-Port Retro-Fit EZ-EFI® allows owners of multi-port fuel injected applications to experience the benefits of EFI with no limit on horsepower because the system is based on each customer’s supplied injectors. Unlike competitors’ systems, the EZ-EFI® is readily available in dual quad or eight stack induction systems. Meanwhile, the EZ-EFI® Jeep Kit with Inline or In-Tank Fuel Pump Kit is engineered specifically to work with the unique requirements of 1972-1991 Jeep CJ/YJ 4.2L, 6-cylinder applications.
