Nope, i use NGK iridium. Noticable power gains: not much if anything at all
Anything else noticable:
Slightly better gas mileage (imagination?) and car seems to run a little better (throttle response wise) but its too early to tell. expensive little ****** too, cost me $11.00 a piece... but i got the good ones...

I got mine from horsepower sales. i get everything there. Why worry about paying shipping and bad sales reps from summit or jegs... i can get anything (probably more) from horsepower sales, and the manager is my friend so i get excellent customer service, and i never pay shipping and get (usually) better prices.
