Some plugs don't play well with the ion-sensing spark knock circuit on the twin cams...

I just stick with OEM... they are not that expensive and they're pretty easy to change...

I've read that Champion makes HD plugs, and the Champion equivalents are #810, RA8HC plugs. You can buy an 8-Pak for $37...
