Great fit, great replacement for standard filter.
Size: 1 Count (Pack of 1)
Very tight fit, but fit it does. I put this in my 2.5L Ford Escape Hybrid 2020. Fits tight, but well, so no wiggling.

Consistently high quality products
Size: 1 Count (Pack of 1)
Have used both their cabin and engine filters for all of my vehicles and will continue with each new vehicle I get. I like that they last a LONG time, are reusable (washable), and help the vehicle run better.

A very tight fit
Size: 1 Count (Pack of 1)
I purchased this for my 2022 Escape, It is the same part listed on the KN website, I watched a video on You-tube on how to replace it. The process seemed simple enough, but I'm not as talented as the poster. I finally got the damper unhooked on the right of the door and the two clips that hold the glove box in were easy to push in. This let the glove box fall forward, Now to remove the two phillips screws that secure door of the filter assembly closed. They weren't too bad, but make sure you have a magnet to get them out, or if they drop to retrieve them. Now the door clips need to be spread apart, I broke the left one, but the right one was ok. Swap the filter and then try to close the door. The new filter was a little too thick front to back and made the door very hard to close. I used the screws to hold the door in place. Close the glove box and try to get the damper back on the peg. Search for this video 2020 - 2022 Ford Escape How to Replace Cabin Air Filter

Excellent air quality and value
Size: 1 Count (Pack of 1)
Much better than the standard filter for air quality. Similar price to the ones that are thrown away 2-3 times per year.
