Boost Performance with Airaid 300-637 PowerAid Throttle Body Spacer Review

Easy to install. Best run. Quiet sound. I've had these in the last 4 cars I've owned and I really like them. Some whistled a bit but nothing that some people complain about. It's barely audible at cruising speed and is really the only time I've been able to hear it. There is no "cool turbo" or "belt squeak". I also have a K&N Performance air intake kit which also helps with mileage.

Improved fuel economy by approximately 2mpg after installation. It was very easy to install and not intimidating at all. It has definitely improved my engine's performance, especially for what it is (remember it's just a spacer, not a supercharger or anything crazy). I do hear the "whistle" that people say is part of it, but personally it doesn't bother me and I think it makes the engine sound like it's running smoother. I will definitely buy again and recommend this great easy upgrade

2018 JLUR - I went from 17.5-18 mpg before install to 20.2 after install. I average 19.3 just driving how I want without paying attention, but that's still a 1.5mpg difference. I drive on the highway / city, on a normal lift and tires. I said 5 stars for the value because I get my money back within the lifespan of my ownership. This time the part I put in my jeep gives me my money back. It doesn't seem to be a problem. I also installed a K&N 63-1576 performance intake system with a rotomolded…

I noticed a slight increase in throttle response. increased miles per gallon! Smooth idle! My favorite part about this spacer is that it makes a slight whistling noise at about 1/4 throttle while cruising, while my average per gallon before the intake and spacer combined with a cold air intake was 16-17, now I'm cruising at 20 through the City. 22. great product Be sure to disconnect the battery before installation, a very important part of the ECU to relearn how the engine responds with the…

Installed on my 2012 3.6L VVT Charger. It's so easy to install, honestly why not install it? It is paired with an Airaid 351-210 intake system with a SynthaMax dry filter. Today I took it on a short drive (50 miles round trip), it was a country road that went through several towns so the speed was 45-50mph for most of the round trip with a few traffic lights on the way. I noticed better throttle response at low to mid idle. The car's fuel economy mode said I averaged 33mpg on that trip. I read…

I've been buying Airaid throttle body gaskets on all my cars for probably 15 years now. The price of the Airaid throttle body seal has increased significantly compared to the competition. I almost wanted to buy a competitor for half or less than half the money but ended up with Airaid. Whether it was the right decision and spent double or more money than the competition, who knows. In addition to the cost, I was disappointed that they changed the color from red to black. The bright red looked…
