Collection: Spark plug wires and terminals for Harley-Davidson, Indian, and metric custom motorcycles

A single spark decides everything – but for it to ignite at precisely the right moment, the ignition cable must conduct electricity flawlessly. Ignition cables (spark plug wires) deliver high-voltage current from the ignition coil or magneto to the spark plug. An aged, uninsulated, or high-resistance cable can lead to a weak spark, misfiring, or rough idling – problems that many unnecessarily attribute to larger faults, when in reality, a simple cable replacement would solve them. Our selection includes ignition cables and cable ends for Harley-Davidson, Indian, and metric custom motorcycles, ranging from factory-specification versions to performance cables with higher heat resistance and lower resistance. Cables of various lengths are available, as well as complete cable end kits – connectors, terminals, sealing rings – which make creating a custom-sized cable simple and reliable. Quality cables and end components ensure stable electrical connection, heat resistance, and durable, long-term operation, even under high thermal stress and continuous vibration. Whether you're replacing an aged ignition cable, performing a complete ignition system overhaul, or custom wiring, you'll find the parts here that reliably deliver the spark where it's needed.
