    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

    High millage JK Unlimited. My 2007 Wrangler unlimited 4x4 with the 3.8 has 216,000 miles and was wondering if this could have any adverse effect due to the high millage? It runs great as is but I would like a little more power without any problems added.

    • Hello, you shouldn't have any problem by adding the Airaid PowerAid Throttle Body Spacer (07-11 Wrangler JK w/ 3.8L) on the contrary, you should expect to enhance low to mid-range power, improve torque, and increase fuel efficiency.

    Is this compatible with the Rugged Ridge high/low mount snorkel? Also wondering if you would/could do a dyno test with various set ups such as snorkels and throttle bodies, seperate and together? This would be very helpful in making a more informed and educated purchase. Thanks and awesome job!

    • The Airaid PowerAid Throttle Body Spacer is compatible with the XHD High/Low mount snorkel. At this time there are no plans for dyno testing the various snorkel setups and throttle bodies/spacers.

      Positive Feedback

      The product is top quality and so, so easy to install... couldn't be happier with Extreme Terrain as a company but to be completely honest, I've not felt a difference in performance since I installed the spacer. Could be to soon to tell as I've only had it in for a few days but overall, the risk is worth the money.

      Not bad, minor gains

      Not much change if any in fuel mileage. Maybe 1 mpg improvement. Minor improvement during initial acceleration from stand still. No whistling noise at all from my 3.8L JK after install. My only gripe is it makes the throttle body stick out further making it a close clearance with other parts. I had to grind a small corner tab on outside edge on throttle body because it was colliding with head of a bolt nearby. It didn't affect mating surfaces, but it was necessary to slide it into proper position.

      airaid price was alright for being american made

      Install for product is pretty easy, temperature sensor is harder to take off if you have a cold air intake , be sure to keep factory gasket on or you'll have code errors on the computer , Id recommend another person to help you install this if your jeep is lifted as its hard to reach in there and hold the the throttle body and do it yourself. Most noticeable gains is about 0-20mph it does go a little faster, fuel economy did get slightly better

      Every little bit helps!

      Easy install, seems like a wee bit better fuel economy, a noticeable performance with low end torque. I already installed an Air Aid intake system so I don’t think there is much more I can do economically to inhance performance for this gutless wounded of a pig 8.6 engine.

      Not bad

      When installed you can hear more air being pulled in, but the gains are so small it's not noticable even with the Airaid intake. still, over time it'll help

      The PowerAid throttle body spacer was a really simple install on my 2008 Rubicon. I installed the spacer with the AirAid cold air synthmax dry filter and right of the bat I could feel the added power. My Jeep sits on 35’s and before adding the two products it had a little trouble getting up to speed and really had to give it a lot of gas. For gas mileage I didn’t see much of a change but that was expected with the lift and bigger tires. But I am satisfied over all with this purchase and have recommended it to my fellow Jeep buddies.
