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!!

Jeep Rubicon 4.0L Jet Spacer

Reviewed By Charles B (Ocala, FL) Reviewed for a 2004 Jeep Wrangler —12/5/2017 4:05 AM

Very easy to install. Did not say which side up but assumed the sticker are to be read upright. Noticeable crisper throttle response. Some light gain in acceleration and holds cruise speed easier in OD now. Good product and recommend.
