Default What would 2 Steps Colder Be????

I am getting nitrous installed and have to have a spark plug that is two steps colder than stock. (Raptor)
Stock is NGK DPR8EA-9, right? That is what I have been running. If it is not stock, what is? What I really need is just the number/model of spark plug to buy. Thanks alot.

I would just leave the same plug, what kind of nitrous are you getting and when, man that sounds cool are you getting a purge valve too.

I know the 8 in DPR8EA-9 is the heat range. a DPR9EA-9 is one step colder and that's what I run I don't know what they do after 9? Maybe 10 but thats kinda weird Your local shop should know what ya need. But post it after you find out I'm interested.[img]i/expressions/face-icon-small-smile.gif[/img]
