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.
