Easy and perfect fit for 2017 and 2018 Honda CRV with 1.5l engines. You need a Phillips screwdriver to remove the 4 screws holding the airbox. After that you just remove the old one and put the new one in the same orientation and put the screws back on. Helps the engine breathe which can result in slightly more power and mpg. I recommend changing every few years.

Looks identical to the OEM

Changed this filter in a matter of 3 -4 minutes. The fit and feel seems identical to the Honda OEM filter---feels just as heavy and fit exactly. For $10 it's a bargain. I drove about 20 miles after installing, also with no problems. 4 stars because I want to give a long term report... I will report a few months from now to advise how it held up under North East conditions.
