Anyone have any experience with these kinds of plugs, two-wheel, four-wheel, whatever?? If you scroll through the application guide, they've got an applicable spark plug model for the Bonneville and America, so was just curious. Seems like they'd be an interesting experirment, though how they would compare to NGK iridiums, or the bosch platinum+4's would be anyone's guess.
