    Review & Installation Video

    Review & Install Video

    Now, throttle body spacers are a little bit controversial. Some people think that they have a large effect, others think that they don't have as much of an effect on your engine. But it really comes down to you and what you wanna use your Jeep for. If you've done other power adders, if this is something that you're adding on just to squeeze that little bit of extra out of your Jeep, then it's gonna be an option for you. Now, there are going to be a couple different versions of this throttle body spacer, one for those of you with the 2007 to 2011 3.8 liter, and one for those of you with a 2012 and up 3.6 liter. So, make sure you get the right spacer for your Jeep. Today we're going to talk through the installation of this throttle body spacer, which is a very simple one out of three wrench install. Even though this is something that's on the engine and some of you might be a little bit worried whether or not you can do this in your driveway, it's a very, very simple install, will take less than an hour to do, and anyone can do it in their driveway, but we'll talk more about that install in just a second.The idea behind the throttle body spacer is to spin the air as it goes into the engine which will accelerate it allowing you to get more air and therefore more fuel into the engine, giving you more power. Now, you might notice this in the way of fuel efficiency, of a little bit of additional throttle response, or actual horse power especially at the top end of the RPM range which unfortunately isn't an area that we spend a ton of time in. If you've just installed 33s or big 35 inch tires on your Jeep and you don't like that down on power feeling that you have, I wouldn't go with the throttle body spacer right off the bat. You're gonna wanna go ahead and regear the Jeep, get it back to the factory final drive ratio before going ahead and adding other power adders. But again, if you've already done a bunch of stuff, you want to squeeze that little extra bit out, this is gonna be an option for you.Now, this one from AIRAID is going to be one of the more expensive throttle body spacers that we have on this site. There is an option out there that's about $100 less expensive than this one. However, this has that Helix design on the inside of it. Really designed to spin the air and cram as much air into the engine as possible, where that other version doesn't have that. This spacer is made out of an aircraft quality 6061-T6 aluminum which is a very high-quality material. It's going to be very strong and very lightweight, but then again this is just a throttle body spacer, it doesn't need to hold up to a lot of wear and tear. This comes covered with a red anodized finish, which is a nice feature, it keeps the aluminum from oxidizing. This is also going to come with all of the hardware that you're going to need to get it installed because you are going to need some longer bolts once you have the spacer installed.Now as I said before, this does have AIRAID's patented Helix design. It has that corkscrew pattern on the inside of the throttle body spacer really designed to spin the air and that's something that you're not going to get from some of the other throttle body spacer manufacturers out there. Like I said before, this is something that anybody can get installed in their driveway. It's a very simple one out of three wrench install and it'll take you less than an hour to get bolted up.Now, the first step in the process is going to be removing the ambient air temperature sensor out of the intake tube so that you can then unbolt the clamps that hold the intake tube in place and get it out of the way. Once it's moved, it's really just a matter of removing the four bolts that are holding the throttle body down. Completely remove it, place your gasket, your throttle body spacer in place, put the throttle body back down on top of that, and use the longer, included bolts to get everything torqued down. Once it's tight, just reinstalled that air intake tube and your ambient air temperature sensor and you're finished. Again, even if you're not somebody who's comfortable doing engine work, this is something that you can very easily do. It's just a couple of bolts, very simple to install.This spacer is going to run you right around $140 and it is a very high-quality spacer. It's very well built, it's going to fit right, it has the red anodized finish on it, and it has that Helix on the inside of it, designed to spin the air, that some of the less expensive options do not have. If you've added a lot of other power adders, you want a throttle body spacer to squeeze every last little bit of power out of your engine, and you have the budget for it, I think this is a really well-built choice.So, if you've already done some work to get as much power out of your Jeep as possible and you want every last drop, adding a throttle body spacer can help with some throttle response, some torque, a little bit of power, and as long as you have the budget for it, this is gonna be an easy install.So, that's my review of the AIRAID Powerade throttle body spacer fitting your 2007 and up JK that you can find right here at

        why doesn't the factory put this on if its so good???

        • There are plenty of products that would be advantageous if installed that do not come factory. However, not everybody wants the positives that a device like this would supply, so Airaid offers it aftermarket for those interested.

            Love the whistle

            I installed this throttle body spacer when I was upgrading my air intake system. Super simple and straightforward to install. The mounting hardware is high quality stainless, and the actual color of the spacer is dope! The Jeep now definitely has a little increased throttle response and she now whistles when I accelerate up from 3000rpm.

            It was an easy install. Took about a hour and 30 minutes to install only because I installed a cold air intake with it. I immediately felt the difference in my throttle response. Worth every penny.

            This is about the easiest install you could do, maybe on-par with affixing your registration sticker. I got *maybe* a 0.3 mpg increase. So if that’s what you are looking for, it’s probably not the answer.

            Airaid Throttle Body Spacer

            Installed along with a cold air intake. I gained my throttle response back to original if not better from adding the additional weight from bumpers and rock sliders. Yes there is a whistle noise but has the same tone as if a turbo was mounted on the engine. Of course I don’t have a lift or tires yet but made a recent trip to my home from school and it only used up half a tank instead of the usual 3/4 of a tank. This coupled with a cold air intake allows your engine to breath allowing for the correct air to fuel ratio to generate power so yes there is horse power gains and fuel economy but must be combined with other parts to reach full potential.

            To install a Throttle Body Spacer or not.

            I have heard the pro's and the con's on Throttle Body spacers. And I thought I would have to see for myself. I installed the Airaid spacer and after 2 weeks of day to day driving back and forth to my job I couldn't believe my eyes. Before the spacer was installed I was getting 15.8 mpg after the spacer was installed I was getting 17.3 mpg. That's 1.5 mpg improvement. So I think that it was worth the money.

            I bought this along with the best Air Intake I could buy. I was so excited when it came. It was very easy to install. You do need to be extremely careful with the Air Sensor as it is very fragile. It looks beautiful on my Jeep. I love it and would recommend it for anyone that wants a quick easy upgrade.
