A filter suitable for use, for example, as an air filter for filtering the combustion air for internal combustion engines, having a substantially hollow cylindrical filter insert, preferably made of a pleated or fan folded filter medium, and end disks disposed at the axial end faces. A plurality of spacing contours distributed around the circumference and protruding radially beyond the projected end face are disposed in the region of one end disk in such a way that the spacing contours contact an inner housing wall of an associated filter housing when the filter insert is installed.
