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.

This filter fit perfectly! I have a 2023 Civic Touring with about 25,000 miles. I bought it new with 2 years of service, and when I went to the dealer for my last free oil change they wanted to charge me $135 to replace my engine air filter and my cabin air filter. Ouch! I have replaced air filters before so I knew it would be a fairly easy job. I was done in about 5 minutes and the filter material is as good as the original Honda filter I replaced.

Great product

These are very good filters and the price is great. I have found that replacing both these filters at the same time works well for me
