Sorry, I should have been more clear. The OEM Harley plugs are a great option for those of us who do not want to gap our spark plugs prior to installing them.
Hemi's are dual plug? Didn't know that, ya learned me good today
I remember a Nissan(?) bastard truck I had with 8 plugs in a 4cyl. Certainly didn't make that one go faster thats for sure!
