A filter element has a filter medium body with inflow side and outflow side at opposite sides relative to a longitudinal center axis of the filter element. A circumferential seal at the filter medium body extends around the longitudinal center axis. At least two projection regions being part of one or more projection elements are arranged at a radially outer side of the filter element axially between the circumferential seal and the outflow side. At least one projection region is closer to the circumferential seal than at least one other projection region and arranged at a larger radial distance to the longitudinal center axis than the other projection region. When connected in a filter housing, the projection regions are placed against a mating structure of the filter housing to form an axial stop of the filter element in the filter housing relative to the longitudinal center axis.
