[QUOTE="charismaticmegafauna, post: 303926, member: 665"] bg2B: An NGK '8' is warmer than an NGK '9' -- that is, (for NGKs) a '9' will conduct more BTUs per unit of time into the head and cooling system than an '8'. Other brand numbering systems may be different. Whether this (conducting more BTUs out of the combustion chamber) will result in a cooler running engine (or, coolness anywhere?) is, I think, still debatable...... ;) There are reasons for the heat conductivity of spark plugs (generally, combustion related) -- but, I think, none of these reasons would be overall engine temperature? jmho :huh: [/QUOTE]
