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.
