Try to cross referance NGK-D8EA its a 8-heat rated plug, but available at any auto parts store, they might be able to just tell you what can be run that is the same. but a 9-rated plug.

Note the XB heads are ment to be run with a 8 heat rated plug. Just a thought but if your having issues, what plugs are you running?

Hi,the plugs that I have gotten before are H-D 10r12a,that is what H-D says to use.

The ngk iridium plugs are less likely to foul as well.
