Abstract

An air intake device for an internal combustion engine which includes at least one collection manifold and intake ducts branching off separately to individual cylinders of the internal combustion engine. The intake lines extend to the collection manifold and are formed at least partially of a flexible tube, especially a rubber tube. The intake lines furthermore have stiff or variable-length portions which are divided into at least two segments disposed for movement independently of one another.
