The main difference between hot and cold plugs?
Let me preface by saying I know this is probably a question that has been asked before but I could not find it in the threads so my apologies if this is one of the repetitive ones.
What is the exact difference between hot and cold plugs and what's the advantage or disadvantage in using it in my 1800 C?
I am currently running the OEM NGK iridium. I don't mean to start the whole what is the best spark plug debate but I just wanted to know the main differences between the two in my specific application?
