20 Best Spark Plug Wires For Harley Davidson (2023 Updated)

The spark plug wires for Harley Davidson are responsible for providing the spark that ignites the air/fuel mixture in the engine cylinders. The spark plug wires are made of a copper core and an insulated outer casing.

The copper core conducts the electricity from the ignition coil to the spark plugs. The insulated outer casing protects the copper core from interference and also helps to prevent the spark from jumping to adjacent wires or other metal objects.
