Anyone one using this plug NGK CR9EIX Iridium IX? If so what is your opinion of it? Currently I am still using the original one that came with the bike.

I switched to the Brisk plug, and I really like it:

I'm using the spark plug mentioned in the first post. Like a lot of people, there isn't a huge discernable difference, but Donna does seem to run a little smoother.

I'll post some numbers related to speed, efficiency, and acceleration when I'm at work a little later if I have some time!
