Spark Plug Question

[clatla]

I have been reading posts and it seems that the plug to use is the NGK CR10EK. I was looking online and I see the new ones are a 4 electrode plug. Has anyone ran these? Should I look for the single electrode ones?

BTW I have a 09 Nytro MTX.

Thanks in advance

I'm running them...couldn't tell you what the difference is but figured I would give it a try! Mine have 4 electrodes. Supposedly Ulmer Racing found a couple hp with changing to these plugs when dyno testing at DTR.
