    Has BP7ES plugs. I realize the "P" denotes that the electrode extends farther. into the combustion chamber The bike is ported, piped, carbed, etc. Built by Dune Trash Racing out of Wichita, KS. Is the "P" necessary. I mean... a performance gain?? Or just stupid thinking?

    I got noticeably less performance from the "P" type plugs.
