The system has an air feed opening, at least one opening for outputting air to an internal combustion engine, whereby it consists of a thermoplastic material and is made of at least two parts that are joined by friction welding. Peripheral contact surfaces are provided on both parts to form the weld seam (18) with a capture edge (14) parallel to the seam on at least one part and a screening edge (24) also parallel to the seam, whereby the second part has a contact surface in the region near the capture edge. An independent claim is also included for a method of manufacturing an induction system. |
