Rough Country Throttle Body Spacer for Jeep Wrangler JK/JL&JT | 3.6L - 10561,Black

I was able to get it installed in less than 15 minutes! My Gladiator seems to have better throttle response. There is a faint noticable whistling noise, but it isn't loud. After driving a few weeks with it installed, I've noticed a small gain in MPG when driving on the highway. 24-25 mpg with the spacer installed vs. 21-22 without it. I don't expect everyone to have the same results, but I have noticed small gains.

I installed this throttle body spacer on my 2015 Jeep Wrangler when I also installed a "Cold Air Intake Kit with Heat Shield". Installation of the spacer itself is pretty easy and does not take long. Between this and the intake, I am getting about 2mpg better than what I previously had. Additionally, when accelerating at a moderate to aggressive rate, the engine has a deeper growl than the stock setup. The whistle is a bit weird, though. Not sure I like that aspect, but for better MPG, I'll put up with it.

Easy install seems to have more throttle response

Let me start by saying if you're in the market to put a throttle body spacer on a 3.6 Pentastar then look no more. Honestly, I don't see a reason to look further and spend more, everything about this kit is really good. If I had any complaint, it would be I'd prefer to see a fiber gasket than a cork gasket included as I'm not a fan of cork gaskets but besides that I think this does everything you would want from a spacer. I used this on a 4th gen Ram 1500 3.6 with a K&N cold air intake as well as catch can and two things were very obvious after installation, one the low-end torque and response absolutely seems to have improved and the whistle everyone talks about is real and very much sounds like you have a boosted V6 at certain throttle positions so that's kind of fun. I know many people call these spacers snake oil and being I can't prove anything not having a dyno sheet to show it but I can say for the money I thought why the heck not seeing it's 2022 and a 1/4 tank of gas cost more than this thing and I personally feel like it produces some increase in performance so I'm happy that I did it.

I didn’t have high expectations, but after installing it (though I wish the manual had more detailed instructions, like clarifying which side the seal goes on—plus, the black-and-white photos weren’t very clear), the throttle response improved incredibly! My Jeep Gladiator used to have a lazy throttle response, but now it’s so much better. Great buy!

I installed this on my 2016 Jeep Wrangler and noticed a difference in throttle response the second I drove out of the garage. Now, I think it is very important to set proper expectations when you purchase and install. This is not going to be a dramatic change. The positive changes in throttle response is minor, but noticeable. Jeeps are notorious for having a "heavy pedal" type feeling. The throttle body spacer smooths out the feeling of the pedal, specifically when starting from a stopped position. There is the sound of the known "Whistle", but I consider it more of a "swooshing" sound, which is the air being pushed through the spacer. I will be installing a cold air intake as well, but wanted to test this spacer on its own. For a very affordable part, I'd say its well worth it, even if the gains are minor. Install was a breeze with no hurdles. Completed the install start to finish in about 15 min.

Not sure what I expected to gain from this spacer. All the reviews are very positive, saying one would notice increased torque, and fuel mileage. Upon arrival it was very well packaged and received in a timely manner. The actual product was a beautiful piece of red aluminum that easily bolted up to the jeep engine giving a very nice visual. Unfortunately this product was a nothing more than a “snake oil sale”. Other than looking fancy under the hood, I experienced no improved gas mileage. I experienced no increase in torque and there was no noticeable power. The only thing I noticed was an whistle under acceleration. which some people reported liking, I am not one of those people, I found it rather annoying. Perhaps it was just me and maybe you’ll have better luck with the product. This just wasn’t a product for me or my jeep.

I confess that I was a bit skeptical when reading reviews about throttle body spacers. I bought one to try it out. It is a keeper. I do not know if it increased power. What it did do is dramatically increase MPG if you have a manual transmission. I have a 2022 Sport 3.6 Pentstar with 6 speed manual. The spacer in my experience increases throttle response significantly between 1500 and 2000 to 2200 rpms. This is important because in the past if I was running 70 MPH in 6th and there was any mild elevation change I would have to shift down to 5th to hold the speed. I do not have to do that anymore. It will hold 6th gear which gives you the advantage of a much taller gear and better mileage. The bottom line that due to this i have probably increased my average MPG by about 3 mpg. It will hold other gears as well allowing you to stay in a higher gear longer which significantly improves mileage.
