Very affordable and fits like the factory one. Don’t pay the dealer hundreds! Just do it your self.

Not compatible with Honda CRV 2023
Style: 1.5L, Style: 1.5L
Pretty disappointed that the description did not match what my car actually needed. THIS IS NOT COMPATIBLE WITH A HONDA 2023 CRV Engine Air filter… Just glad the cabin air filter worked. Having to buy another one… The image attached is what I needed to replace.

Perfect fit and high quality.
Size: (Pack of 1)
Good product, not much to say. The product arrived quickly, looks to be of high quality construction, fit perfectly and took me only a couple of minutes to install. I love it when a product is no frills and delivers as advertised. I've used various filters from K&N before and have always had very good success with them so I will be buying more of these for sure when the time comes.
