Review on Enhance Performance: Throttle Body Spacer 1068 for Jeep Wrangler TJ YJ 87-06, Cherokee XJ 84-01 by Todd Adams

I have a 99 TJ with 2.5l. For the price I thought I couldn't go wrong. I just installed it (took 45 minutes with lots of cleaning/dusting) and the SOP dyno (trouser seat) says it works on a short test drive. I never calculated gas mileage, but this is a gas blank before installation, it doesn't get any worse. The pictures in the instructions were a little silly, but if you take it apart you can figure out how to put it back together. Head for 10, a screwdriver and a vacuum cleaner.
