i think its 10$ for 1 plug...80$ for 8 plugs....they'd have to last a LOOOOONGGGG time for me to think they'd be worth it.

35,000 on it, probably not, unless you do alot of WOT driving. I just changed mine like at 64,500.

Sounds like a gimmick. Mags tend to pump their sponsor's products, so take claims like that with a grain of salt. 3.3hp is hard to accurately measure. Dyno's aren't accurate enough for that. I'd want to see multiple tests showing the same gains repeatedly.

As far as plugs, if you're spending over $2/plug, you're getting reamed.
