ABSTRACT:
An ignition coil includes a primary coil carrying primary coil body, a low voltage connection area and a secondary coil inductively coupled with the primary coil for the provision of a high voltage for a spark plug of the combustion engine. The secondary coil is carried on a secondary coil body concentrically enclosed by the primary coil body. A high voltage connection area is provided, in which the secondary coil contacts the spark plug. The secondary coil body encloses a cylindrical, magnetic core, and primary coil body and secondary coil body are both surrounded by an electrically and magnetically conductive shell. The shell includes a longitudinal slit therethrough. The primary coil includes an uneven number of layers. A remote extending coil lead from the low voltage connection is led along the longitudinal slit of the shell. The coil lead runs at least partially within the outer perimeter of the shell.
