Abstract

An air routing system, especially an air intake system of an internal combustion engine, which makes optimal use of available installation space by integrating a bypass channel (25) into an air intake module (10). The volume of the bypass channel also provides an acoustic shield for the collector chamber or plenum (22). The free area (13) behind the mounting flange (11) that is required for screwing in mounting bolts in order to mount the air intake module (10) is used by an air intake hood (14) which can be installed on the filter housing (15) after the air intake module has been mounted. This assures that there is a greater volume available in the filter housing (15), thereby reducing the noise at the inlet opening of the air intake module.
