Spark plug wires should be replaced every 50,000 kilometers. Spark plug wires are an essential part of the traditional ignition system, serving as the medium through which the ignition coil transfers energy to the spark plugs. When symptoms such as engine shaking or jerking occur, it is crucial to inspect the spark plug wires and replace them if necessary. Automotive spark plug wires, also known as ignition wires or spark plug cables, distribute the ignition sequence and transmit the high-voltage spark from the distributor to the spark plugs, enabling combustion in the cylinders and driving the engine's rotation. Spark plug wires generally consist of four parts: conductive material, insulating rubber, ignition coil connector, and spark plug connector. Some spark plug wires are also wrapped with a layer of heat-resistant material to prevent damage from excessive heat.
