Abstract:
The invention relates to a filter element (18), a filter housing of an air filter and an air filter, in particular of an internal combustion engine, in particular of a motor vehicle, in particular of a utility vehicle. The filter element (18) has at least one filter medium (46) for filtering air. The at least one filter medium at least partially surrounds an element interior with respect to an element axis. The filter element (18) can be arranged in the filter housing, which can be opened and which has at least one inlet for air to be purified and at least one outlet (22) for purified air, in such a way that the filter element can be replaced and the filter element separates the at least one inlet from the at least one outlet (22). The filter element (18) has at least one element-side supporting element (58) on an outside facing away from the element interior on at least one end face running axially with respect to the element axis. The supporting element (58) comprises at least one element-supporting section (60, 62). At least when the filter element (18) is installed in the filter housing, the end face of the at least one element-supporting section facing axially away from the element interior has an uneven surface contour.
