Both are unclean bodies. Top is bored with sensors and hardware on, but unclean.  Bottom is stripped of all sensors and hardware ready for glass-blasting.
NEW!!  87-91 Bored Out Throttle bodies are enlarged from the factory 52mm to a much more pleasing 58mm.  92-01 4.0L engines have benefited from a larger throttle body for many years. They use a 60mm throttle body to guide air into the engine, which is one of the ways Chrysler made the performance increase from "low-Output" to "Hi-Output" engines in 1991.

Horsepower increase is easily noticeable, as well as an increase in mileage if the power is used in moderation. Throttle response is much crisper.

All throttle bodies are Glass bead blasted and precision bored.  Custom made throttle plates are found in each of our throttle bodies.

Instructions are included with each body.

Installation time is approx 25 minutes with little or no mechanical experience necessary.

No affects to computer.
