Great fit, and lot more more robust in build than the OEM filter it replaces. I've replaced the factory cabin air filters in at least 3 vehicles with these, when the time came to replace. Side note: This one went into a 2020 Lincoln Aviator and --consistent with my experience with previous Lincoln models -- the retaining tabs on the filter housing door snapped off when I was trying to remove it. Nothing to do with the K&N filter, but I just don't understand why Lincoln can't design a better housing door mechanism.

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.
