If you want to increase the throttle response on your Jeep, upgrading the fuel injection system is a good solution. Replacing the stock fuel injection with an aftermarket brand also will improve fuel economy. 4WD carries the Howell brand for standard fuel injection kits and the Edelbrock brand for electronic fuel injection kits. Each brand offers the complete kit made up of well manufactured parts. The materials are solid cast iron and applications offered include fuel injection systems for AMC V8 engines of Jeeps from model years 1970 to 1991.
