ABSTRACT:
An ignition coil includes a connecting device for contacting a spark plug of an internal combustion engine, the connecting device being designed to have a sleeve made of insulating material. The sleeve is able to be connected at a first end section to a high voltage side of the ignition coil, and at a second end section has an accommodation for the spark plug. Furthermore, in the sleeve at least one conductive contact part, touching the spark plug, is situated for the electrical connection of the ignition coil to the spark plug. At the high voltage side of the ignition coil, between it and the spark plug, a plurality of electrically conductive modular components are able to be positioned, which in the installed state are connected in a detachable, electrically conducting manner.
