Works and is inexpensive
Used this for a 2019 Honda CRV, works and saved us a lot of money over getting it at the dealer. Easy to install.

Did not fit 2018 CRV 2.4L
This did not fit our 2018 CRV 2.4L, at all. Yes u know it's the engine air filter and not the cabin air filter. We replaced them both and this didn't fit. I ordered another one from a different listing and it fit like a glove.

Perfect Fit 2019 Honda CRV
I have a 2019 Honda CRV AWD and this filter fit perfectly. It looks exactly the same as the filter that was previously installed by Honda. I’ll be buying these and installing myself from now on!

Looks like engine air filter, it’s smaller than needed; but needs to be compared. Haven’t looked at air cabin yet
