A casting tool for an air intake duct includes a mold and exchangeable extractable cores for the formation of a cavity. The exchangeable extractable cores are provided for the mold, by which, while retaining the mold as such, different air intake duct geometries, especially different air intake channel cross sections, can be produced. In this manner a plurality of intake duct variants can be produced at substantially constant tool costs. This permits the economical use of injection molded synthetic resin air intake ducts, since the very expensive casting tools can be provided for a sufficient number of air intake ducts.
