Suction system for an internal combustion engine

An intake system with a modular design for an internal combustion engine comprising:

• a) a plastic air distributor module which comprises a one-piece air distributor top part module and a one piece air distributor bottom part module which can be coupled to the intake system of an internal combustion engine;
• b) a plurality of one piece plastic intake manifold modules each being formed separate from said plastic air distributor module, said manifold modules having a first pipe end and a second end wherein said first pipe end is coupled to said plastic air distributor module and each being assigned to one combustion chamber of the internal combustion engine;
• and
• c) at least two plastic flange modules coupled to at least one of said intake manifold modules at said second end, wherein said at least two plastic flange modules can be mounted on the internal combustion engine and are each assigned to one cylinder block of the internal combustion engine, wherein said plurality of one piece plastic intake manifold modules which are arranged side by side, are connected to one of said at least two plastic flange modules and then to another of said at least two plastic flange modules in an alternating manner.
