Plug read, opinions needed

The only thing that comes to mind right now is that a member here was using very cold marine iridium plugs in what was described as a boosted application that had problems with exhaust charge contamination.

If you can find guidance for a safe point of which plug to start with it may be worth it to see if they read any differently.
