I have a 04/1200R with Sreaming Eagle pipes and re-jeted,plus S/E air cleaner, stock plugs are Harley 6R12 plugs. Any suggestions for different plugs.:stir Thanks, Bill

Your "mods" are minimal in the engine world and a change in heat range isn't necessary. If you've changed compression, cams, displacement or all the above, then it might be an issue. I'm not into "gimmick" spark plugs.

I have to bookmark that. I paid 17 bucks for the platinum Harley plugs last time and 10 for the gold. Rip off!

Kainam, Thanks for the chart, I think I'll keep it in my truck so when I hit the local car stores I can have it ready for reference. To many numbers to remember. Spad:1drink
