the only way a spark plug can increase power is if you were missfiring on the old plugs.

I remember reading once how some guys were on the dyno and they changed out their old spark-plugs for some new, "high-tech" ones. They found 5, or so hp...and then they swapped in some new, stock ones and the power stayed the same! They later concluded that ANY new spark plug will make power over OLD, stock plugs.
...something to think about before you pay all that money.

I've actually seen "convincing" dyno sheets in magazines i trust. Mostly because some engines picked up 4-5HP, some picked up 1 tops. Of the top of my head, one stock car picked up 8hp or so, i believe an RX-7. Anyway, I don't think it's the same BS as alot of the performance plugs on the market, and i'm skeptical with these types of mods. But, i'm going to have to guess our motors would be on the low end too.
