The MSD 8.5MM Super Conductor Wire’s extremely low resistance with high Electro Magnetic Interference suppression is a combination that defies the common laws of physics. Less resistance means more energy is delivered to the plugs, which helps burn the fuel mixture completely for more power. With less that 50 ohms per foot, the 8.5mm wire is capable of delivering 30 times more spark energy to plug over most OEM wires. This low resistance is produced by a copper-alloy material, which has excellent voltage carrying capabilities as well as strength. For the outer sleeve of the Super Conductor MSD uses a proprietary combination of silicone and synthetic material. This produces a wire with resistance to high heat, tearing and chemicals. The tough sleeve also provides a solid foundation to crimp the terminals, delivering the highest terminal pull-off strength of any other performance wire. Many different custom length sets are available as well as universal sets that you custom tailor to match your application.
