what plug 450?

What plug is everyone running? cr8e ? i took the plug out of my bike today and it was really in there.it took some twisting before it would break loose.

I am using a CR9EK

The K is a twin electrode, we cant get an 8 here but the 9 is a cooler plug and everyone here uses it

NGK CR8E is what I use. :)

NGK CR8E I have a whole bunch of them mine as well keep using them. :)

My dealer told me too use Denso U24ESR-N instead of the NKG CR8E
