Spark Plug Wires, also known as ignition cables, are designed to conduct voltage from the ignition coil or distributor to the spark plugs. These wires arc across the gap from each plug's center electrode to the side electrode for the proper ignition of the air/fuel mixture in the cylinders. A spark plug wire features conductive material sheathed in insulation that is covered by an outer, heat-resistant, protective layer. It has a metal terminal at one end that fits over the spark plug terminal and one at the other which connects into the distributor cap tower or ignition coil. Each end cover has to enclose the terminals and assist in keeping the wires in place.
