RN12YC Champion plugs. Have Champions for eons and not had a problem with them. They Have been the OEM plugs on Mopars for as long as I can remember and I have been involve with Mopars for 40 + years.
Clean it, if it's Dirty. Oil it, if it Squeaks.
But: Don't fix it, if it Works!

The 65 is close to a N14Y champion which is a hotter plug. Performance engines usually need a colder range plug. From what I remember a 64 plug is closer to a N12Y champion. Mike

A colder plug dissipates heat at a faster rate which makes it run cooler. A hotter plug dissipates heat slower so it runs hotter.
I have had bad luck with champions and will never run them again. Autolite only for me.
