Moroso ignition wire set for GM LS/LT engines features Ultra 40 8.5mm wires at 9.75-inch length with an aluminum heatshield in red. Intended as a direct-fit plug wire replacement, this set routes ignition to spark plugs while the included heatshield helps guard the wires from elevated under-hood temperatures, making it suitable for street or mildly modified LS/LT installations where proper wire routing and heat protection are needed.
