[QUOTE="jarance, post: 417284, member: 21"] No doubt copper is the best conductor but the principle of arcing in the combustion chamber is thru high voltage which is step up via the ignition coil. If you observe careful, the spark from the spark plug actually flash over from the tip of the plug to the body via the air gap of the spark plug. So where is the 'good conductor" between the tip and the body? [/QUOTE]
