regular or fancy plugs

Hey all

Is there any advantage to using gold or platinum hd plugs vs the regular hd plugs?
Gas milage? Performance? Anything??

Thanks

Dennis

I wouldn't run any HD plug!! I run NGK Irridium plugs. That is the plug the Local Harley davidson drag bikes run.

RE: regular or fancy plugs

I ran the HD regulars that came in the bike to 6500 miles. I got a sudden miss. I replaed them with the same and got a miss about 6500 miles later. I replaced those with HD platinums. I ran those plugs for over 30k. The bike was running fine on them when I replaced them last summer after doing some engine upgrades and wanted to monitor the burn on a new set of plugs.
