I'm about to change the spark plugs for the first time on my 7.5K miles Hayabusa.  My question to you is:  Is there a better spark plug than the recomended by the manaufacturer?

I am running irridiums in my '01, but I am not sure if they are any better. No noticable difference, but if you want the best, there are none better than irridium. About $12 each though!!!

Why do you think they are the best??? Is it because they are long lasting or do they increase performance in some way???

Better spark plugs aren't necessarily going to increase performance but they will increase reliability. Irridium has the best corrosion resistance and therefore won't foul up as easily.
