Great Value
Style: PA99892
Great value. Dealer wants $75 to replace engine filter. The filter is just as good as the OEM one. Total time to install is less than 3 minutes.

fits like OEM
Style: PA99892
This fits a 2023 Civic Sport Touring without issue. It looks indistinguishable to the OEM filter. Getting the lid off the airbox is the hardest part as it is wedged in there pretty good. Other than that, this is a very do-able DIY job, and it's a lot cheaper than having the dealer do it. I have no concerns. Thumbs up.
