Derrick, I have tried several brands but always went back to the Champion's. I always had much better luck with the RJ9Ys the 12s are awful hot. Herb 1963 Fury 2D/HT ?

Hi All, I'm sure this has been covered before but.............. Running a 426 MW, 11:1 compression. Running Champion plugs (RJ12s). The car sees street driving and the occasional street bracket nights. Any other plugs recommended? I'm thinking its time for replacement and wondering of others Experiences. Any preferences out there? And/ or should I be running a hotter or colder plug? Thanks in advance.
