Got this to replace cabin air filter on 2020 Honda Civic Sport, as it said it was a direct fit… It does fit but not perfectly! Holding it next to the filter you can see the size difference, with the original being slightly longer. I noticed a whistling sound from the AC at full blast right after install. I believe this noise is caused by the small gap left in the retainer box with the slightly smaller filter. Luckily it is not incredibly loud, but it’s still there. The quality of filtration seems to be much better than stock filter, but the fitment not exact for vehicles mentioned above.
