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

First of all I want to say that this product is amazing! My Jeep slowed down at high speeds. I've noticed with my Jeep that throttle response has greatly improved, it no longer feels sluggish and feels a lot better under acceleration, however as a side note I haven't noticed any drastic changes in fuel economy. It's more or less the same plus or minus 5 extra miles per tank of fuel, but you really can't beat the price!
