Anyone using AR133 autolights?
I try to always use AC delco plugs in my firebird. But my new dart heads require the AR133 or equivilant. But the number didnt cross over to any other brands so i bought the autolights. Are these good plugs?

They are a "racing" plug. We have them at work (advance). They are pretty much the same except they have the tip cut back. It is supposed to get a better spark since it is exposed.
Autolites aren't bad plugs. I would give them a try.
