Abstract

The intake air filter (10) according to the invention is for cleaning intake air for internal combustion engines, in particular in vehicles. To this end, the intake air filter (10) includes an openable housing (11) with an inlet (16) and an outlet (17). Disposed between the inlet (16) and the outlet (17) is a filter element (18). In order to check, when the housing (11) is closed, whether a correct filter element (18) has been properly installed, a filter element identification device is provided, which, designed as a dome (28), corresponds to an additional opening (29) in the housing (11).
