A spark plug Wire Harness, also known as an ignition wire loom or high tension lead, is an important component in the ignition system of a vehicle. The wire assembly is responsible for transmitting the electrical current from the ignition coil to the spark plug, which in turn ignites the fuel in the engine.

The spark plug Wiring Harness is typically made up of a core of conductive material, such as copper or carbon, surrounded by a layer of insulation. The insulation is designed to protect the wire from damage and prevent electrical interference from other components in the engine.

Over time, the insulation on the spark plug wiring loom can become worn or damaged, leading to reduced performance and potentially even engine misfires. It is important to regularly inspect the wiring assembly for signs of wear and replace it if necessary.

When replacing a spark plug Cable Assembly, it is important to use a Cable Harness that is designed specifically for your vehicle's make and model. Using the wrong cable loom can lead to poor performance and even engine damage.
