An ignition module that is adapted to be mounted on an internal combustion engine and which is operative to electrically connect the secondary winding of an ignition coil to a spark plug of the engine is described comprising, a housing formed of electrical insulating material having a wall that faces the spark plug when the module is mounted on an engine, a metallic cover secured to the housing, an ignition coil disposed within the housing and a cover with a laminated magnetic core and a secondary winding. The magnetic core is clamped between the housing and the metallic cover with a portion of the core directly engaging the cover whereby the core has a direct heat transfer path to the cover and is electrically connected to the cover. A tubular member is formed of insulating material secured to the wall. The tubular member carries a conductor means that is adapted to engage a terminal of a spark plug. The tubular member is positioned to slip over the spark plug when the module is assembled to the engine, and means connecting the secondary winding to the conductor means that is carried by the tubular member and which is adapted to engage a terminal of the spark plug.
