Spark Plug Wires
Your car’s Ignition Wires transfer an electric pulse from your Ignition distributor, or in some cases individual coil packs, to the spark plug; which in turn ignites the compressed fuel air mixture in your engine’s combustion chamber. As your spark plug wires age, they build resistance and do not transfer the electric pulse as well as they used to. This is mostly due to contact corrosion, and deterioration of the insulated coating or jacket on the wires. If the insulated coating on the wires is cracked or torn the electric pulse may arc to other parts of your engine causing a misfire. You should replace your ignition wires as recommended by your car’s manufacturer. Most manufacturers recommend replacing your spark plug wires between 50,000 to 60,000 miles. It is also a good idea to replace your wires when you are replacing spark plugs, tuning up your car, or replacing other major ignition components such as the distributor or coil.
