NGK’s are a waste. All those fancy iridium plugs etc. are made for one reason. 100,000 mile plug changes. Other then that they have no advantage. IMHO that is.
I don’t see how they are a waste as they cost 1.50 a plug on rockauto, A couple cents more than autolite copper. I agree with you about all the fancy stuff, I just picked them because they were cheap and seemed like a decent set of plugs.
I don’t want to get into up spark plug brand debate, there’s pages of that in the forum already. I was just curious if anyone had some actual experience with spark plugs in a warmed over smog 360 running pump gas.
May be 1 step hotter than what is recommended. Champions were stock. Some swear by Autolites and NGK. Your choice. I would look up by application first then Cross reference the original plug number just to be safe.
