The spark plug doesn't control how much fuel is sent to the cylinder. It simply creates a spark. Some may add that a good efficent spark will conserve fuel, but, I'm thinking the primary means to affect fuel milage is through the fuel management.
Just my thoughts.

Just some more snake oil. The plain old standard spark plug will do just as well and last just as long as the overpriced ones. I know some will disagree, but I think even platinum plugs are a waste of money in our scoots if you follow your maintainence schedule.

E 3 plugs.
I used to run E3 plugs in my 99 ultra. I didn't notice any change either. I took it in to Harley for an electrical problem and they told me that Harleys do not run good with E3 plugs. It also voids the warranty. My warranty has been out for years and I'm not sure if they are saying that to sell their plugs or not. To be on the safe side, I stopped using them.
