Re: Spark Plugs

Thanks for the AL website. It's a great resource.
However, the AL web site does NOT give ANY information on HOW TO READ THE HEAT RANGE. (or i couldn;t find any such nomenclature/documentation/instructions/prose/rhyme nor reason in the AL website regarding ANY deciphering of plug characteristics whatsoever in any way shape form or fashion).

Let me put it another way:

If one is handed at random some RANDOM spark plug that is NOT AC Delco then how does one determine CHARATERISTICS of the plug???? I'll even limit it to how does one determine the HEAT RANGE ONLY of the NON AC Delco plug????

I have checked a few Autolite books and they sometimes give very sketchy rules for deciphering the plug number. Sketchy at best. Other brands nearly non-existent info.

Bottom line:
One must be able or have some kind of intructions or decodeing chart or table or SOMETHING to determine the characteristic of the plug that one is physically holding in their hand and viewing with their own eye in real time of the real world.

To the best of my knowledge AC Delco plugs are the only plugs that satisfy the above criteria.
