851-447 Direct Replacement Premium Dry Air Filter

Won’t get any HP or TQ from this filter, won’t even get more noise. But it’s reusable, and easy to clean (and no need to oil it!). Got it for my 21 Ram EcoDiesel and dropped it right in, can’t say much more about a filter. It filters.

I have a 2012 RAM 1500 Quad-Cab HEMI. I read tons of forums, and reviews before buying my drop in Airaid filter. I had reasonable expectations that I would hear a better sound, and that's about it. I didn't expect more horsepower, or better fuel mileage. It would have been nice to have a slightly better response too. I have noticed a slight, nice, difference in tone.I'm guessing there's more throttle response since I am getting slightly less MPS's. I know since I like the better sound, I like to hear it more by getting on it more.The main reason I kept this and didn't return it is because at around a steady 30 mph, I could hear a high pitched noise. After dropping in the Airaid in, it's completely gone. I took the Airaid out and put the stock filter back in, and sure enough the noise came back. So, I'm definitely keeping this.

Love the product. I would have left 5 stars but Amazon put k&n stickers in the Air Aid box. So I contacted Air Aid and they are sending me the right stickers. So Amazon cost Air Aid a 5 star.

Replaced the basic air filter in my 2016 Rebel. Uncertain on throttle response improvement but getting slightly better mpg after install. A little expensive but a nice improvement

Looks and appear very durable. I dropped it in last night and I saw more of my Eco light today. Don't expect a huge difference, just peace of mind.

It helps out alot when towing a trailer

I didn't notice any change to the mileage or engine sound. With that said, this is a quality filter that drops into the stock intake.
