When you are pushing a high-performance Softail engine, you need a spark that can keep up. These Sumax 409 Series spark plug wire sets are built for professional racing applications where maximum spark delivery is a must. Sold as a set, these 10.4mm wires feature a heavy-duty construction with three layers of silicone and a tightly woven, heat-treated fiberglass skin. They boast a dielectric strength of over 100,000 volts, ensuring no energy is lost before it hits the plug. The spiral-wound core is protected by a Taylor Pro Boot bonded directly to the wire, making this a rugged and reliable choice for any performance-oriented build.
