DIY, super easy to replace.
Fit 2018 crv. I like to change out my air filters before taking my car to the dealership for an oil change. Saves a ton of money to DIY. Easy to do perfect fit.

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.
