Spark plug heat range/carbon buildup

Thanks - I'm finally at a computer where I can view the chart; The last couple of collumns appear to be not brands, but thread sizes and such - confusing since you'd think that info would be in a horizontal row - not sure if that's referencing some or all of the brands. It's a bit wide to print out, but I'm going to try and print the most pertinent info to take with me to NAPA tomorrow.

*edit* that's one HUGE list - I'm suprised they don't have a search option, or the ability to look in numerical order. I haven't been able to find 2400 series plugs yet, and the library's closing..
