A retaining apparatus is provided for mating an ignition coil to a spark plug.

Ignition coil to spark plug mating apparatus

An ignition coil assembly of the type which is directly mounted onto an associated internal combustion engine spark plug. The coil assembly includes a spark plug boot section made of a highly elastic material with an inside cylindrical passageway. The inside passageway features ribs which engage a high voltage connection coil spring positioned in the passageway to make an electrical connection between the coil and spark plug high voltage terminals. The spring has a generally constant outside diameter outer section except its end segments have a reduced diameter where they contact the high voltage terminals. The passageway ribs retain the spring in position prior to its installation and after its removal from the associated spark plug.
