ABSTRACT:
An ignition coil for spark ignited internal combustion engines intended for mounting on and connection to a spark plug which simplifies high voltage distribution, promotes maintenance and safety, lessens radio interference, and reduces exhaust emissions. The ignition coil preferably has a tight fitting resilient insulating boot engaging the spark plug. The boot member preferably has an air passage with a contaminate filter for facilitating the insertion of the boot on the spark plug. One embodiment includes a grounding member connected to the ground lead of the primary winding of the ignition coil which engages either the grounded portion of the spark plug or the cylinder head for grounding the primary winding of ignition coil.
