My 2005 Wrangler TJ is my first jeep. I put a 2.5" lift on it after I got it, just to raise the jeep off the 18" tires a bit. It only has a 4 cylinder, but is great for cruising around. Love going topless and rolling thru the country. Just wondering how to get a little more power from the 4 cylinder, when on the highways. Dpes anyone have any suggestions.
