(54)Ignition apparatus having conductive plastic ignition terminal and field smoother


(57) An ignition apparatus includes a high voltage (HV) terminal to which a high voltage end of the secondary winding is attached. The ignition apparatus further includes an electrically conductive cup configured to surround the high voltage terminal when the secondary winding spool is inserted in the case. The high voltage terminal has one end that comes into engagement with an inner annular surface of the cup. Electromagnetic interference suppression is provided by a resistor disposed between the cup and a high voltage connector assembly that connects to a spark plug. The resistor is formed of electrically conductive plastic material.
