Hi John! Hows it going? I was wondering what you were up to, just lurking? LOL! I have no complaints about the VX plugs whatsoever. I have them gapped at between .032 and .034. Can't tell much difference at this range, but way better than OEM gaps. No hesitation, or stumbling, and power throughout the rpm range. For the price, I don't think they can be beat. The gap is a huge diff. after I re-gapped the Splitfires to .034, they felt light years better, but I would stay with the VX's for the platinum and therefore presumably longer lifespan.
