Perfect Fit for Honda Accord 2024 hybrid Touring

Fit 2025 Honda crv hybrid sport l
These fit my 2025 Honda crv hybrid sport-l perfectly. They are much more economical than having the shop replace them. I wish it said what the composition is- cotton or otherwise, because I have read you should oil cotton filters to work as intended. I didn't oil them amd so far haven't had any problems, but time will tell.
They are a great value for the money and work as described. I would recommend these if you want to save some money on parts and labor for replacing your air filters. There are some good videos online that show you how step by step.
I haven't noticed any odors or lack of durability since installing them.

Perfect replacement filters.
Size: CRV 2023-26 2.0L Hybird
These filters are so close to OEM that you cannot tell the difference. I would not be surprised if they also make the OEM filters. I am completely satisfied with this product.
