FAST is now offering its EZ-EFI kits for 1972 to 1991 Jeeps with the 4.2L I-6. Switching to an EFI system over the troublesome factory carb set up is night and day in terms of performance. Check out the details below.
The new EZ-EFI Jeep Kit is engineered specifically to work with the unique requirements of 1972-1991 Jeep CJ/YJ 4.2L 6 Cylinder applications. An exclusive FAST™ adapter plate for the patent pending throttle body eliminates the need to replace or modify manifolds, making this the only truly easy, bolt-on EFI kit on the market today for 1972-1991 Jeeps.
Once installed, the system is completely self tuning as you drive; there is no laptop or tuning experience necessary. The kit contains an adapter plate and throttle body, weatherproof ECU, wiring harness, hand-held device and everything required for installation. Equally suited for both highway or off-road driving, the kit is also available with inline or in-tank fuel pump.
