which spark plug
Hi
I have a 2015 sportster 883 low. It has had the S&S 1200 conversion kit installed, Screaming Eagle 551 cams, V&H short shots with super quiet baffles, screaming Eagle high performance air cleaner and a direct link tuner. my question is what spark plugs should I use, the stock plugs or which suggestions please
Thanks

What does S&S recommend?
Curiously I fitted NGK DCPR7E plugs in a standard 2008 Custom 1200 and the indy I went to recommended I put the HD 6R12 plugs in as he has had failures with NGK but none with HD.

Use the Goldie Lock ones, not too hot and not too cold, just right.
Way too many factors for each mod and how you ride. May have to do some medium and high speed runs but with todays fuels it`s very hard to get a plug reading. Go on the cold side and if you are fouling go up a heat range
