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.

Great replacement filters
I’m onto round 2, almost due for round three of filter and oil changes on my eco diesel JL and so far these have worked great because i refuse to pay $50 for just an oil filter. No oil pressure issues with the oil filters and fuel filters prime and work as they should.
