Almost 2 years and 20K on the MKC, so I replaced the cabin air filter today (Motorcraft FP-70).
As noted by Psychoart, the MKC cover lacks the nice release fasteners used on the Escape and instead uses simple Christmas-tree type clips. I broke 2 of the 3 clips in the removal process. I think the intention is to remove the fasteners with the cover; doing so might salvage them. I replaced all 3 with removable push-pull fasteners from NAPA, which should considerably ease the process next time.
Only about half of the filter access opening is visible, so maneuvering the replacement filter into the housing is a combination of feel and luck. Mine went into position without much difficulty.
The old filter was grisly--lots of embedded dirt and even some mold. 20K seems too long an interval. Next time, I'll replace the filter at about 7.5K miles.
