The induction pipe, the heating module and the cylinder head delimit at least one intake port in which at least one electrically heatable heating element is arranged which constitutes a component of the heating module. The heating module is connectable with connecting terminals to an electric current source and the joining surfaces between the induction pipe, the heating module and the cylinder head are sealed by a sealing device. The heating module includes at least one thin plate made of metallic material. A conductor made of electrically conductive material is secured on the plate. The sealing devices are constructed in one piece with the heating module on the side facing the induction pipe and the side facing the cylinder head.
