Rock-It Parts HI-Flow Throtle Body for 94-98 Jeep Grand Cherokee ZJ with V8 Engine

If You've taken care of the major airflow restriction with a hi-flow air intake system then the next bottleneck in your engine's air restriction is at the throttle body. The throttle body on your 1991 and up Wrangler is tapered down on the backside of the throttle body base plate. The small diameter bore on the throttle body makes it restrictive. The Rock-It Hi-Flow Throttle Body is machined for a larger bore diameter, allowing greater airflow.
