Why is anti-seize lubricant necessary on spark plugs? Someone, who builds 60-70's Chevy engines said to never use it. Because the anti-seize can be conductive and the anti-seize can also mess up the gap of the plug. Therefore it will degrade the performance of the spark plug.
All I can say in return is that the manuals say to use it. I don't know why, though. Could someone please give me explanations or references on why it is necessary? I would really appreciate it!
