Is there a difference in spark plug wires?
The true difference between these sets of plug wires lay in the resistance of the wires. The carbon core wire had a much higher resistance rating and limited the amount of electrical charge that was passed to the spark plugs. Because of this, resistance rating became the standard when comparing spark plug wires.
