Haven't seen spark plug wires like these before.
hahahahah! ive done this before! heavy gauge copper wire right? it works great! just dont touch them.
gosh thats wonderful.
I like these by one of the members of the Flatland T's of Kansas Chapter...
Just DO NOT USE modern plug wire made with carbon instead of solid wires. The carbon is for radio interference suppression for you modern car's radio but putting resistance in the line between the coil and spark plug on a T results in a ruined coil in short order since the high voltage will look for an easier path to ground than the high resistance spark plug wire. It is exactly like powering up a T coil with no suitable gap connected to it's spark plug connection point.
