The filter bellows has a first axial end and a second oppositely positioned axial end. The filter bellows has a notch at least at one of the first and second axial ends. An axial length of the notch in longitudinal direction is shorter than a longitudinal extension of the filter bellows. The support pipe has a support structure at the axial end with the notch and has at least two wings. The support structure is oriented radially away from the support pipe and is integrated into the end disk at both sides of the notch. A filter system with such a filter element arranged in a housing is provided.
