I did some measurements on the NGK 94201 vs stock Champion.
Insulator thickness at the end of the threaded section
NGK 4.77mm
Champion 4.33 mm
Depth of insulator nose (from electrode strap measuring to inside of the threaded section)
NGK has 2mm less depth compared to the Champion plug
NGK has a shorter, thicker insulator nose and should be colder than the Champion.
