Abstract
An ignition module that is adapted to be secured to an internal combustion engine. The module has a plastic housing and a metallic cover that is adapted to be secured to an engine. A plurality of ignition coils are located within the housing and cover. The lower wall of the plastic housing has conductors embedded therein that electrically connect the secondary windings of the coils to electrical connector assemblies that are carried by the housing and which are adapted to slip over the spark plugs of an engine. The connector assemblies include means for making an electrical connection to the terminals of the spark plugs. The ignition coils have laminated cores that are clamped between the housing and the cover. The cores directly contact the metallic cover so that the cores have a heat transfer path to the cover and are electrically connected to the cover.
