Abstract

An air routing system includes an air filter for cleaning intake air having a clean air outlet a compressor for compressing aspirated intake air an intermediate line connected between the clean air outlet of the filter and the compressor, and an intake module. The intake module includes a plenum with a clean air inlet for compressed intake air at least one intake pope connected to the plenum and a bypass line for excess compressed filtered air. The bypass line has an inlet to a channel segment of the intake module for uncompressed clean air upstream of the compressor, and the bypass line is at least partly integrated into the intake module such that a volume of the bypass line at least partly surrounds the plenum.
