Dodge spark plug wires are part of the vehicle ignition system, helping to provide the high voltage spark necessary to complete the engine combustion process. The engine needs three vital ingredients for combustion, air, fuel and high voltage spark. The fuel and air are delivered to the combustion chambers in a balanced mixture, where the high voltage spark will ignite them, beginning the combustion process.

The coil produces the high voltage spark that the engine needs, sending it to the distributor through a heavily insulated high voltage wire. The distributor transmits the voltage to a series of electrical contacts, which in turn send it to the spark plug wires.

The Dodge 4x4 spark plug wires will carry the high voltage to the spark plug positioned at each engine cylinder, giving them the power to produce the spark that ignites the fuel and air mixture in the combustion chambers. Each of the spark plug wires is fitted with a heavily insulated and moisture resistant protective jacket, designed to keep the power they transmit contained. At the end of each one of the spark plug wires is a fitted rubber boot that attaches securely to the end of the spark plug, forming the connection that transmits the high voltage from the wire to the spark plug. The spark plug wires must be replaced at regular intervals to maintain the efficiency of the ignition system, as the high voltage they transmit will gradually wear on them, causing deterioration.
