Abstract

The invention concerns an intake system, in particular an intake pipe of thermoplastic plastics for the intake air of an internal combustion engine with in particular cylinder rows arranged in a V-shape. The intake system comprises at least two elements (10, 14), the first element (10) having a substantially closed shape and simultaneously forming the lower half-shell of the intake pipes. The second element (14) is designed as the upper half-shell of the intake pipes and is connected to the first element (10) by the plastics welding technique.
