Abstract: An internal combustion engine ignition distributor cap is premolded into an integral unit of electrically nonconductive material having a top portion, a plurality of output terminal towers, each having an axial bore, extending outwardly from and circumferentially arranged about the outer surface of the top portion and a peripheral wall portion. An insert member of an electrically conductive material having an electrical contact surface on at least one end thereof is inserted into the axial bore of each of the prior molded output terminal towers with the end thereof having the electrical contact surface extending into the space within the cap as defined by the inner surfaces of the top and peripheral wall portions. An output terminal of an electrically conductive material is electrically connected to the end of each of the insert members opposite the end thereof located within the space within the cap.
