Spark Plug: Description and Operation
Spark plugs provide the path for high secondary ignition system voltage to flow to ground. It is this current, arcing between plug center and ground electrodes, that creates the
air/fuel mixture ignition spark. Many spark plugs are made with an internal resistor, designed to reduce ignition system electrical interference with entertainment systems and computerized devices.
