Haha, I know its off topic, but...

What brand spark plug?
What's in the engine?
Will it see WOT for any length of time?

My $.02 says go hot. Very rarely do we run into too hot a plug for street cars. Extended tip 5-6 heat range (autolite) spark plugs don't foul easily and will clean up. If somebody runs nitrous or boost we will drop the heat range down into the 3-4 range if we know the dude's gonna use the motor for evil. Cold plugs are a pain in the ass for show cars. They foul so quickly and won't come back even with the "high arc" technique. Early combustion chambers and carbs are really bad for fuel puddling which will kill the plug instantly.



I like the boxed wines!
