40200 8mm spark plug 4 wire set, universal. Black

Designed for dual-plugged heads, this Compu-Fire 8mm spark plug wire set includes four wires with a spiral-wound inner core and a black silicone jacket. This universal kit is designed to be cut to the required length for a custom fit on your machine. It is compatible with both points and electronic ignitions, providing excellent conductivity and insulation. The set includes four plug boots already attached, though you must install the coil boots and terminals yourself. These wires are suitable for Harleys with the traditional coil connection used up to 1999, excluding Twin Cam, Milwaukee-Eight, and 1998 to 2003 XL1200S models. They are an essential upgrade for high-performance engines requiring a dual-plug ignition setup.
