MC-SPW1 Blue Streak, XXX spark plug wire set

Keeping a classic Ironhead on the road requires the right ignition components, and this Blue Streak XXX spark plug wire set is built for 1958 to 1969 Sportster models equipped with magneto ignition. Sold as a set, these 8mm wires feature a traditional copper core, making them suitable only for points-style or magneto systems. The triple silicon jacket and insulation provide superior resistance to high temperatures and engine chemicals, meeting or exceeding all OEM requirements. Finished with factory-style terminals that lock securely onto the spark plugs, these wires offer a performance upgrade that maintains the reliability needed for vintage Harley-Davidson motorcycles.
