C = 10 mm
R =Resistor Type
9 = Middle Heat Range (Range from 2 (hot)-11(cold))
E = Thread Reach 19 mm (3/4")
K = 2 Ground Electrodes
I am not sure what you are comparing the plug to but the info above came out of my NGK Book at the Shop...hope it helps.

what is the deal with this plug? Is it hotter or colder or the same?
What is the power gain on a stock engine?
Are the gains tried true and proven?
Why does it make more power?

RE: CR9EK
The numerical equivalent NGK part number for the CR9EK is 4548. Auto parts store will have it cheaper ($5.49 each) than bike shops ($10 + each).

RE: CR9EK
As far as heat ranges go, domestic manufacturers = higher numbers are hotter (ex. autolite 25 is one range colder than 26) while import manufacturers are the opposite (ex ngk br8es is one hotter than br9es).
