ULTRA Spark Plug Wires :: 90-93

ULTRA 8mm Red Hot Ignition Wire Sets utilize silicone rubber for both the 8mm wire insulation and boots, with a minimum rating of 100,000 volts in all areas. The silicone rubber is designed to withstand continuous temperatures ranging from -60 degrees F to +480 degrees F. Brass "screw-together" connectors are double-crimped onto the zinc-clad, stranded copper wire ends to provide absolute contact with no possibility of deterioration. The silicone boots seal watertight at the spark plugs and ignition coil for added protection. A unique design feature seals a wire wound resistor inside the spark plug terminal to optimize noise suppression and power.
