Spiro-Pro Series Wires Surpass the Competition in Performance and Looks

The Spiro-Pro's two-layer 100% silicone inner core and outer jacket keep the wires flexible for the life of your vehicle, maintaining its vibrant color with heat protection to 600 degrees F. These ignition wires consist of a highly-conductive, spiral-wound core with a stainless steel wire covered with conductive fluorocarbon material. 350 ohms per foot resistance provides more fire power to the spark plugs than OE resistor core wires and has up to 10 times less resistance than standard resistor core wires. They're also available in a choice of three colors: black, blue, and red.
