Koolsox™ is an impressive new double layered fiberglass sock designed to add extra protection to exposed spark plug boots and wires. The sock provides an easy visible way to detect potential burn areas before they occur. The sock absorbs the burn instead of the wire so no misfire occurs. An adjustable ring allows the unique sock to be rotated for longer life. Soft and very flexible, you'll find Koolsox™ adapts and stretches over irregular surfaces.
