I agree... exactly how far back are they supposed to be ground? And how much difference does it make if I have MSD 8.5mm wires and a Crane Fireball coil?

They used to sell plugs that way.. I think they were called "J" plugs??
But old time hot hodders used to grind back the outer electrode to about half way. So looking at the plugs eletrodes, the outer one will only be over half of the center electrode.


Almost like the precusor to the splitfire plugs.
