The aim of the invention is to ensure an increased specified three-dimensional stability of a molded body (100) for conducting air for a motor. According to the invention, this is achieved in that the molded body (100) has an inner reinforcement (11) and an outer reinforcement (13). The inner reinforcement (11) and the outer reinforcement (13) are arranged at a distance from each other in the direction of the thickness (15) of the molded body (100). In particular, the molded body (100) is to be developed such that the placement direction of the outer reinforcement (13) is configured in a freely defined manner along the contour of the molded body (100). Furthermore, the production of conventional injection molded outer contours and contours is to be facilitated by virtue of the combination of an inner mandrel extrusion process and an injection molding method, said contours providing the molded body (100) with additional properties and functionalities. These are, among others, clamp seats, mounting flanges, platforms, ridges, saddles, as well as inserts made of different materials (metals, plastics, etc.), which are inserted and overmolded.
