Abstract
An air filter for a fresh-air system of an internal combustion engine may include a filter housing, a filter element, and an inner shroud. The filter element may be arranged in the filter housing and may include an annular filter body, a first end plate, and a second end plate. The inner shroud may be arranged in the filter housing and may be rotatable about a longitudinal center axis of the filter housing. A first torque coupling may be disposed between the first end plate and an end wall of the inner shroud. The first torque coupling may have a driver contour on an inner side of the first end plate and a counterpart driver contour disposed on an outer side of the end wall. The driver contour may be engaged axially in the counterpart driver contour and facilitate torque transmission between the end wall and the first end plate.
