    I had this installed on my 88 Jeep Grand Wagoneer's AMC 360. It is absolutely the best upgrade I've made to the rig. Completely transformed the Jeep into something I want to drive every day. What else can you put on your Jeep that gives you more power AND better gas mileage? Also, I got the C.A.R.B. legal version to help me pass smog.

    Manufacturer

    Howell Engine Developments, Inc. was formed in 1988 by two brothers who wanted to turn their passion for classic cars into their career. The company focuses on producing fuel injection systems to upgrade classic Jeeps that were made in model years before on-board computers were standard. Howell Engine Developments produces wiring harnesses that don't require Jeep owners to be electricians or computer programmers to successfully install in their classic Jeeps. Classic Jeeps can now access the increased fuel economy and heightened performance of an ECM controlled fuel injection system without the Jeep owner accessing headaches while installing the upgrade.
