I don't have a good answer for this one. With a good ignition system almost any spark plud will work. Some people seem to like the NGK's. I often get what is on sale and is the stock replacement plug, then check to see if I need to run a hotter or cooler spark plug.

I run the superseaded part number for the Champs. It's almost the same number.
MoPar used to carry the plugs just a few years back.

Champion RJ12YC..... should be stocked at your local parts store...
I've tried Accel's (NGK).... Autolites, etc... and the ole cheap Champions worked great as did the others, but the Champions where cheaper...

PS: I'm running a 440 .040 over at 9.5:1 compression...
