Bone stock. Plenty of guys on here that have "upgraded " plugs and/or wires and led to problems. If it ain't broke............

Standard Harley pugs. Anything more expensive is a waste of money.

I stick with the HD 6R12's. That is one of the only four things that I use from HD.

Standard HD plugs for me. I tried a set of jobber ones. Can't remember if it was NGK or Champion. Bike kept throwing codes. Switched back to HD's and all was good. I'm not going to lie it kind of ticks me off

Standard HD plugs , they last twice as long as change interval. All those fancy magic plugs are just hype.

I'll have to admit to buying a set of NGK Iridium plugs. Then I noticed they were slightly longer than the HD plugs so I just went ahead and purchased more HD plugs and put em in. The NGK's are in my "WTF was I thinking" trophy case along with a bunch of other stuff.
