Perfect fit
Size: 2023-26 CRV 1.5L Gas
This filter set was a perfect fit for my vehicle and installed without any issues. Everything lined up exactly as expected, which made the replacement quick and straightforward. The quality feels comparable to the original filters, and it is a great option if you are looking for a direct replacement without overpaying at the dealership. Overall, this is a reliable and easy upgrade for routine maintenance. I would use this again.

Save money, buy non oem
Size: 2023-26 CRV 1.5L Gas
This Engine Cabin Air Filter Set is designed specifically for Honda CRV 1.5L Gas models from 2023 through 2026 and Honda Civic 1.5L Gas models from 2022 through 2026. It is important to note that this filter set does NOT fit the 2.0L engine variants. The filters replace the OEM part numbers 17220-64A-A00 and 80291-T5R-A01, ensuring a proper fit and function. That being said, however, the AIR FILTER does fit the 2017-2021 CRV

Same quality as oem
Size: 2023-26 CRV 1.5L Gas
This is same quality as oem. Very much similar. The only difference is that this cabin filter has activated carbon which reduces the cabin unpleasant odor. Very easy to install. The price is affordable. I save money on this doing DIY.

Fits 2023 Jeep GC 4xe
I purchased this filter based on another review that mentioned it being a perfect fit for a 2023 Jeep Grand Cherokee 4xe, and can confirm that it does fit perfectly! My partner smokes in the Jeep sometimes and the air conditioning was starting to smell so I'm hopeful that having the added carbon in this filter will help reduce that smell. I'm a bit disappointed, I was told when I bought the vehicle that it had some "special" air filtration but that was not the case.. the filter I pulled out looked just like any other basic filter you'd find in any vehicle. I would assume from comparing the new filter that it will do a better job (with addition of carbon and foam around the filter for a better seal). Very easy to install, just had to release the cord on the left side of the glove box and the filter fits right behind there.
