These metallic braided ignition wires deliver maximum spark energy while providing a Pro Street look. Armor Shield wire sets enhance the appearance of braided fuel lines and coolant hoses. Featuring silicone spark plug boots, yellow and blue silicone wires, and zinc-plated steel spark plug terminals, these wires benefits from an efficient transmitter of ignition energy and oversized upgrade from the OEM 7mm wires. The core is made of carbon/graphite conductive materials which is high resistance to suppression and is rated at 3000-7000 Ohms per foot resistance.
