Colder Spark Plugs Stop Pinging?

I've had no issues with champions. Always used them even when I had the slant 6.
I live in a really hot, and high traffic area, my bike with a S@S B and .565 cams liked them better, so did all my over cammed and over carbed Mopars, PLEASE Don't think I am taking Your thread that way. They just seem to not get as gas fouled. My Apologies
