    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.
