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 ( ) into an air intake module ( ). The volume of the bypass channel also provides an acoustic shield for the collector chamber or plenum ( ). The free area ( ) behind the mounting flange ( ) that is required for screwing in mounting bolts in order to mount the air intake module ( ) is used by an air intake hood ( ) which can be installed on the filter housing ( ) after the air intake module has been mounted. This assures that there is a greater volume available in the filter housing ( ), thereby reducing the noise at the inlet opening of the air intake module.
