    See Emissions Details
The special copper alloy conductor is strong enough to handle the high current and voltage of the magneto, plus is a much better conductor than stainless steel. Even with its low resistance, the Super Conductor retains extremely high Electro Magnetic Interference (EMI) suppression abilities. By tightly winding the conductor around the ferro-magnetic impregnated center core, the wire creates an EMI "choke" holding the noise inside the wire while delivering the strongest spark possible.
