Abstract
The intake air filter according to the invention is for cleaning intake air for internal combustion engines, in particular in vehicles. To this end, the intake air filter comprises an openable housing () with an inlet () and an outlet (). Disposed between the inlet () and the outlet () is an annular, closed main filter element () and an annular, closed secondary element (). The secondary element () is connected to the outlet (), whereby no contamination can pass through to the outlet () when the main filter element () is replaced. A centering device () is provided on the end face opposite the outlet () between the secondary element () and the main filter element (), said centering device being used to fix the position of the secondary element () within the main filter element (). This prevents relative movements between the main filter element () and the secondary element ().
