      can this be used in conjunction with a throttle body spacer

      • The Airaid EconoAid Throttle Body Booster (07-11 Wrangler JK w/ 3.8L) is designed to spin the air similar to most throttle body spacers. Airaid has not tested using the Throttle Body Booster with a throttle body spacer so they do not recommend combining the two.

          5 2008 Wrangler - Macho Installation Time: Less than 1 Hour


          The fit on the gasket was a little off but other than that it was stupid easy to install and I saw the performance and MPG improve after a day or so. I went from getting 16MPG average to 18.5MPG. Doesn't seem like a lot, but when you drive a Jeep Wrangler it counts. Solid Purchase.

          Econo aid

          I have have noticed some improvement in fuel economy. I also installed a cold air intake at the same time. I have gone from 15 mpg to 17.1 mpg. I have also noticed a better throttle response and sound.

          Best bang for your buck

          I monitored my mpg for one week after I installed an air intake, and noticed more power and about 1 mpg difference, then I put on Airaid EconoAid throttle body booster, monitored for another week and noticed alot more power and another 1.5 mpg. Very happy with the throttle body booster. Bang for your buck, you can't go wrong, worth every penny. 2010 JK.

          Love it!

          My 2011 3.8 needed a boost. I noticed less down shifting and saw 1.8 mpg difference in the first tank. Doesn't seem like much but I'll take it.

          5 2007 Rubicon Unlimited - RubiconRaiderFan Installation Time: Less than 1 Hour

          Inexpensive easy low end power adder

          I installed this EconoAid throttle body booster on my ’07 JK Rubicon. I had already installed a cat-back 3” exhaust system, and an intake system with a washable air filter. I suppose that there were some performance improvements with these mods, but nothing like the immediately noticeable change that this product provided. I couldn’t believe the change in acceleration. But that was just the first part. I could not believe the change in performance, especially in the low end, pulling long grades. I live in the Sierra foothills, and there are several spots that I usually have to downshift, and just maintain a steady RPM until I got to the top. Now, I can accelerate up these same hills, in a higher gear than normal. I still can't believe the immediate change! My buddys noticed it right away too. They couldn’t believe that it was just the addition of a throttle body plate, with some fingers pointing inward. With 35" tires, I don't check mileage, so I can't comment on that. Anyway, I would highly recommend this product. Smog legal in California.

          easy to install

          This was easy to install. Took about 15 minutes. Upon first starting after installing noticed the idle was smoother. Test drive, I noticed better throttle response. Have to drive enough to determine if fuel milage is better.

          Happy with this

          This part can only help I did notice an increase in throttle response. I installed it the same time that I installed the banks cold air intake. If nothing else it brought peace of mind that on my budget I'm doing all that I can to improve my performance. As a side note I'm extremely happy with extreme terrain they're shipping and customer service by
