238517 Fits 1986 1999 Fxr and All Evolution Models with Coil Betwee

These Sumax 409 Series spark plug wires are engineered for professional racing and high-performance FXR models. Measuring a massive 10.4mm in diameter, these wires feature three layers of silicone and a heat-treated fiberglass skin for superior thermal protection and durability. The spiral-wound core ensures maximum spark energy reaches the plugs, while the dielectric strength of over 100,000 volts prevents arcing in high-compression engines. Each wire is finished with a bonded Taylor Pro Boot for a factory-quality seal that resists heat and vibration. Sold as a set, these wires are the perfect upgrade for FXR riders who demand the best in ignition technology. They provide the high-voltage delivery needed to keep your engine running at its peak under the most demanding conditions.
