Well mine did, the only place I could get a plug was the dealer. From what I have found out since is you should never have to replace it.
But me being me I have a spare on the bike. I did look around town and every body had it listed but nobody but the dealer had one. One place would not order it unless I took 10 as they had never sold one and did not want 9 leftovers!!!
I now have 5k on the original plug.
