Airaid 300-637 PowerAid Throttle Body Spacer

I Installed this on my 2012 3.6L VVT Charger. It's so easy to install honestly why wouldn't you install this? It's paired with the Airaid 351-210 Intake System with SynthaMax Dry Filter. I took it on a short trip today (50 miles round trip), it was a back road that went through a few towns so driving speed was 45 - 50 mph most of the way there and back with a few stop lights along the way. I noticed better throttle response at low to mid range idle RPMs. The car's fuel economy mode said I got 33 MPG average for that trip. I have read a couple reviews that said the whistle was just too annoying, I didn't notice anything and yes, it's installed correctly. Those people must have really sensitive hearing. Love it and would recommend to a buddy.

I noticed a slight increase in throttle response. there was a increase in miles per gallon! Smoothed out the idling! My favorite part of this spacer is that under about 1/4 throttle while driving it makes a slight whistling noise while pared with a cold air intake my average mpg before intake and spacer was 16-17 now I am at 20-22 driving around town great productBefore installing make sure to disconnect the battery very important part of the ECU relearning how the engine responds with the throttle position sensor!

I have been buying Airaid Throttle Body Spacers for all my vehicles for probably 15 years. The price of Airaid Throttle Body Spacer has gone up substantially compared to the competition. I almost wanted to buy a competitor for half or less than half of the money, but in the end I stuck with Airaid. Whether that was the right decision and spending twice or more money than the competition, who knows. In addition to the cost, the other thing I am disappointed in, was that they changed the color from red to black. The bright red looked cool, the flat black, not at all. As far as ease of installation, took about a half hour or less in most every vehicle including my 2021 Jeep Wrangler Rubicon. As far as performance, I believe that they add a little oomph right off the start. As far as the whistling, I honestly don't notice it.

When I bought this part, I was a little skeptical about the claims they make. Performance-wise, I think their claims are spot on. My mileage was a little better and I did notice throttle response improvement. I used this part in my car for a couple weeks and liked it for the most part. When stomping on the gas, you will hear and feel a little extra "oomph" when your car takes off.Now the part where I returned it. I am not a heavy foot driver nor am I racing my car. This part was designed for that and they did it well. Yes, it did increase my mileage slightly, but there is a catch. The noise. They are proud of the hissing or whistling noise from these things and while at wide open throttle, it does sound great, at low throttle I am not a fan. When you are driving around 20mph in your neighborhood, most drivers make a lot of throttle adjustments. Little more gas, little less, you know what I mean. Everytime the throttle position changes, you get the hiss or whistle sound from the spacer. In all honesty, at low throttle, it sounds like a slipping or squeaking belt. It was this squeaking belt sound that drove me nuts. Here I am cruising through my neighborhood in my new Charger and my neighbors all think my belts are slipping. Not cool, not cool at all. I returned it.The product was easy to install, easy to use, and built well. I appreciate finely machined stuff and this is one of those things that you can tell goes through quite a bit of quality control. Unfortunately for me, it just wasn't for me. I would recommend this to anyone that might be a weekend drag strip fan. It can be installed in minutes and would be well worth the extra little "oomph."

Great product! Gave great addition to torque and sounds real nice! Has a crisp soft whistle. I can only notice it because I have an aftermarket pypes violator exhaust system and I know what I'm listening for. It does a great job took 15 min to put in!

Why 3 stars? Price. A bit too expensive. Works best around 1700 rpms. Barely removed low end hesitation. I am using with k&N cold air intake system. Made well. Easy to install. Have a 2015 Wrangler V6. Seems odd. But fuel MPG dropped a point. Did NOT gain MPG. I'm located 6700 feet above sea level.I would not buy again based on price. It's okay.

I was second guessing myself about purchasing and installing this spacer after reading all the negative reviews. Well the ones that say this does not work, don't waste your money, obviously installed it wrong. My spacer was added to my K&N cold air intake in my 2016 Chrysler 300s 3.6L. I feel a big difference in my throttle response and improved mpg. The K&N CAI already gives me more horse power, the spacer added to it. And the roar of the engine is amazing. Don't read the negative reviews and go with the positive ones.

se ajusta perfectamente a mi ram 1500 DT 2022 3.6 LT V6, acelera muy bien se ve la diferencia lo recomiendo 100 % precio calidad
