NGK iridium plug

does anyone run one of these in there 450? and if so what size?

I run a cr8eix in my 03 450. Have about 50hrs on plug still looks good,starts fine and

runs smooth. My opinon they are worth the extra money.

I run the cr8eix plug also, they say it helps bike start easier and gives it 1 or 2 extra H.P. at mid range , dunno about that but for 10 bucks, I can say it lasts a long time.
