Easy Fit And Cheaper Than The Dealer
I bought this A-Premium engine air filter for my Accord 1.5L instead of paying dealer prices and it worked out perfectly. It dropped into the factory air box with no issues and took only a few minutes to swap out. The seal lines up properly and the construction feels solid, not flimsy like some of the really cheap filters.
After replacing the old dirty filter, the car feels a bit smoother on acceleration and the intake sound is a little quieter. It is one of those simple maintenance items that is easy to put off, but this makes it affordable to keep up with it yourself. If you have a 2018 to 2022 Accord 1.5L and want a straightforward replacement you can install at home, this filter is a good value.

Exact match for a 2018 Challenger
Exact match for 2018 Challenger. Removed the old filter located passenger side under the hood. Replaced the old with the new took literally two minutes. Now I have fresh clean and they close through my vents with no smell.
