Ignition wires deliver the high voltage produced by the coil(s) to each spark plug. However, they are not the only wire utilized on a vehicle. Today's vehicles have several on-board computers that are multiplexed together to form an intricate web of primary wire. They also have sophisticated battery cables, ground straps, and fusible links that deliver the voltage and high amperage necessary to start the engine.
Airtex Premium Ignition Wire sets are the preferred brand of Ignition Wires.
Silicone jacketed wires and silicone spark plug boots are used on most late model vehicles with electronic ignition
