I know I just posted a question about spark plugs myself, but I would be very very wary of any claims of increased performance from a spark plug. The best that you can hope for is an incremental increase in spark intensity or reliability (although increases in intensity usually come at the expense of coil longevity - usually ignition upgrades need to be done as a system, with stock-like plugs but with a wider gap, and beefier coil(s), and OEM plugs under stock conditions have to produce a very reliable spark to meet emissions standards) or longer life. If a manufacturer claims anything more than that, then IMHO it's a fair bet that the manufacturer is sellin' snake oil.
