Good value, fit 2023 CRV 1.5L
These filters arrived wrapped in plastic in a cardboard box, shipped in a standard Amazon box.
Initial quality seems very good. I've previously used store brand filters and oem filters in our 2023 CRV 1.5L, and these look comparable. They fit fine. If you have not changed your filters, there are good youtube videos that show how to do it, the CRV is well supported and pretty straightforward without having to buy a bunch of special tools.
If you don't want to spend $100 at the dealership, these are a good value and only take about 5-10 minutes total to change once you have done it a few times. First time out, give yourself 30 minutes and be patient!

Fits Perfectly. Can't beat the price. Don't Hesitate....
Actually this filter combo fits my customers car perfect. Some after market filters you have to finagle a little to make them fit, however this engine air filter and cabin filter fit perfect...Great deal for both filters.
