Although the plug is female, with a partially recessed center contact, it is still possible for casual accidental contact with a metallic object to short-circuit the power source. The best spark plug wire sets are responsible for delivering high-voltage pulses of electricity to the spark plugs. An entire article can be written on the differences in Spark plug wires.
