I want to put new plugs in my car ahead of SUNI and am getting a little dizzy researching them here and online. I use slightly hotter plugs because my engine tends to run rich and have used NGK B6ES for years, based on a recommendations from another member...9 years ago. That particular plug is no longer available, although NGK says the 4922 BR6ES is a replacement. Champion RN12YC is another plug that has been recommended here before, and another plug that appears to be no longer available.
It has been a while since we had a discussion here on spark plugs. I don't think this is quite the equivalent third rail as oil recommendations, so here goes. Any recommendations?
