Plug wire has a copper alloy conductor that is a much better conductor than stainless steel that some other plug wires use. The sleeve of the plug wire is made from silicone and synthetic material giving it resistance to heat, cleaners and cuts.
Spare plug wire is great to have in case of a fire, worn out ones or one of the other little problems that can occur at the track.
