      Boost Performance. Rugged Ridge makes this Throttle Body Spacer for the latest and greatest Wrangler JK models to help you boost your engine's performance, torque, and horsepower. The large bore spacer raises the throttle body 1 inch above the intake manifold, thus letting your Jeep's engine suck in plenty of cold, dense, power-boosting air. You can install this high quality aluminum spacer in an hour or two using simple hand tools, with no need to drill new holes.

      Durable Construction. With a gasket and all hardware included, the Throttle Body Spacer by Rugged Ridge comes ready to install. Measuring 1 inch in thickness to give a similar lift to the throttle body above the engine manifold, this spacer features a large, smooth bore for pulling in plenty of air. Construction is solid aluminum for toughness and corrosion resistance, further enhanced by a black anodized coating. Rugged Ridge covers this part with a 5 year limited warranty against manufacturing defects.

      Application. This Rugged Ridge Throttle Body Spacer is specifically designed to be used on the 2012-2020 Wrangler JK and JL models equipped with the 3.6L V6 engine.

      Technical Note. This Rugged Ridge Throttle Body Spacer is not legal for use in California or other states adopting California emission standards.

        Nice Addition

        10 minute quick install if you have the tools handy. I noticed a little get up and go with what feels like a tighter throttle as you push the gas pedal in. I also have the pedal commander combination (a must have) and an aftermarket Cold Air Intake.

        A Must Have

        This throttle spacer is great especially if you have an aftermarket breather. Gives you better sound. Install was less that half hour.I don’t know about the gas mileage yet but throttle response feels better. Great upgrade.

        Very easy to install. So far so good. Add the same time as a cold air intake.

        Throttle body spacer

        I bought this with a cold air intake. I can’t seem to tell a huge difference with either one other than the sound. The engine sounds more aggressive under the hood. I can tell a small amount of torque but it’s in mid range when you are taking off from a stop. My mileage has stayed about the same, maybe a touch more. I was at 19.5 now about 19.6. This is after about 800 miles.

        Easy install

        Was getting 18.5 mpg with door and soft top together. Now I heat at least 19 mpg even with no doors or top gear. Rear seat and spare tire have been removed before install

        Try it with a CAI but I returned it immediately. The whistle was terrible when you touched the throttle.

        Looking for more power

        I bought this and a cold air intake at the same time. Installation was fast since I was also installing the cai. Between the two, I seem to have more power but I did no tests.

        Rugged Ridge

        Bought this with Red Rock cold air intake. Nice fitment, installed quick (10 min), does as it's supposed to. After first hour long trip noticed 2 mpg improvement. Not sure if air filter or spacer or both, but best upgrade decision. Recommend this for jeep.

        Throttle Body Spacer!

        Purchased this along with the Rugged Ridge Cold Air Intake System. Easy installation, looks good doesn't have the whining or whistle that most say. With the addition of the Cold Air Intake, there is definitely a difference in the low end torque and a nice sound! Possibly 1-2 MPG gain!
