Doesn't anybody know the answer to my spark plug question? Is this
a dumb, stupid question or does nobody know the answer?
Let me make a guess:
- A "R" at the front means resistor
- The number, like "10", is the heat range
- The "C" used in new Champion numbers just means copper.
So is an 11 a hotter plug? What does the "N" and "Y" stand for? What
other types of plugs are people using in there healeys (NGK, Bosch, etc)?
How do other numbering systems compare?
Thanks again,
PS. I'm glad to see that lots of people are keen to get b-car pictures.
I'll do a bunch of meet pictures this afternoon.
