I have just purchased a 99 Wrangler with a 2.5L. It is completely stock under the hood, and I was looking for some suggestions on what I could do to boost up the power, or what would be the easiest and first things that I should do? Not looking for a hot rod just a little better performance..
Thanks
The first and easiest thing to do, is pop in a new performance aif filter--K & N.
We had already had this discussion....
