NGK BR9EIX, Iridium plug is what I use. It is sure to cause debate but I find the Iridium version gives a substantial improvement over the standard version and worth the extra money.

I tried an iridium plug on my electra X and it only lasted 800 miles. Mind I have had a bit of a problem with plug fouling. Hopefully that is now a thing of the past
