I have a 2011 110 cvo coming up on the 20,000 miles, going to change  spark plugs, anything better than the what the dealer sales? Thanks for any info

Nope IMHO a spark is a spark, use what it came with and you will be just fine.

Stick with the standard 6R12 plugs.  You can spend a whole lot more for the SE plugs or some aftermarket choices, but they won't fire the mixture any better than what came stock.  Don't buy into the advertising hype; there is no "free" power or economy to be found by spending three or four times as much for a plug.

X 2. Different plugs can actually make the bike run worse. Stick with the 6R12.

Right on. I think the standard plugs also have a resistor of some sort that helps prevent spark knock. All those splitfire & +4 (Bosch?) plugs are pure bs ... electricity always takes the path of least resistance so it can't be 2 or 4 different places at once.
