Agreed, these plugs are great. They made a notable difference on my bikes start up, idle & wide open throttle. Very glad I went with them.

Stock Harley plugs (5R6A) are made by Champion and cross reference to Champion RN12YC.
I've never used anything else. Is there any advantage to using iridium plugs other than paying more money?

I use E3's, always had good luck with em too. price is right too (~ $5/ea on amazon.com). P/N for the evo's is E3.34
only downside is they are not gapped out of the box (easy fix though)
