stock style work well for the current ignition/efi system.
some guys who have used "magic" plugs, and even screaming eagle plugs have had drivability problems and codes.
as much as we complain about these bikes, the HD and the automotive world have come leaps and bounds the past 40 years in terms of power, reliability, emissions and MPG
10,000 miles is probably about right for plugs
