2012 Focus Cabin Filter
Just relpaced filter @21K. It was black.
To make it easier to get the new filter in, if you gently squeeze the top & bottom of the filter it decreases the size & provides a rounded leading edge as you insert it. Once you have the leading edge in the filter snaps back to its squared shape.
Did not have to remove fuse box doing it this way.
Who ever designed this should be shot.
