Isuzu spark plug wires are critical to the good performance of your vehicle, assisting in the ignition process that carries the high voltage spark to the engine to contribute to the combustion process. With the assistance of the Isuzu spark plug wires, the ignition system provides high voltage spark to each engine cylinder to ignite the fuel and air mixture in the combustion chambers, beginning the combustion process that produces the engine power that allows your vehicle to function. Isuzu spark plug wires are equipped with a heavily insulated jacket to confine the high voltage they transmit and shield them against the contamination of moisture and vehicle fluids. At the end of each of the Isuzu spark plug wires is a fitted rubber boot that attaches securely to the end of the spark plug at each engine cylinder. These boots form the connection that allows the spark plug to receive the high voltage transmitted through the Isuzu spark plug wires and use it to produce spark for the engine combustion process. The Isuzu spark plug wires will deteriorate over time, their efficiency gradually diminishing from the stress of the high voltage they transmit. Their protective jacket can become brittle and cracked from the heat of the engine or exposure to vehicle fluids, allowing moisture to contaminate. Periodic replacement of worn or damaged Isuzu spark plug wires is necessary to maintain the efficiency of the ignition system.
