Quote: The AR52 are pretty cold for a street car on pump gas If I was going to use the 13/16 size spark plug bodys I would probally use the Autolite 53 or 54, or the resistor plugs in the same heat range( I can't remember those numbers right now )
I just cross referenced the accells that barton had put in it and that was the autolite number. I run c12 at all times so not really sure
