1991 Jeep Wrangler 4.0 HO

Reviewed By brad b (Marysville, WA) Reviewed for a 1991 Jeep Wrangler —7/7/2008 10:26 AM

Installation was a breeze. Sounds like there's a turbo under the hood. Very good horsepower increase. Gas mileage almost doubled. One thing... The screws that come with it are very wimpy. I broke one trying to tighten down the spacer to eliminate the vacuum leak. I just replaced them with higher quality screws and I love the finished product. Great first step in upgrading your engine!!
