I got mine off Flea bay for about $5.00 ea. Just have a look around there, a couple of guys are solid plug merchants. Watch the shipping also!

Not really, go to NGK's website and read up on the theory!
Plus, I'll always believe Ulmer's results.

FAQs - Spark Plugs
Q: Why are there different heat ranges?
A: It is a common misconception that spark plugs create heat. They don't. A heat range refers to how much heat a spark plug is capable of removing from the combustion chamber.
Selecting a spark plug with the proper heat range will insure that the tip will maintain a temperature high enough to prevent fouling yet be cool enough to prevent pre-ignition. While there are many things that can cause pre-ignition, selecting a spark plug in the proper heat range will ensure that the spark plug itself is not a hot spot source.
