I'd just stick with a good NGK in the correct heat range.

Modified magazine did a dyno test on them in a Nissan 350Z and they netted an 11 horse gain. I have read two other articles using different vehicles that showed similar gains. Very impressive for a spark plug change. they do cost $25 each, thats the only downfall

I have them installed im my car right now and so far they are great.
They work as good as or better than stock ones did and they "feel" more responsive and more peppy especially at higher RPM's.
They give me better gas mileage too, I am nearly back to the same MPG's that I had before I changed my differential to 4.56 gears.
I figured the Denso Iridiums I would have gotten to replace the stock plugs would have been about half of what these cost me so why not give these a try....and so far I am not disappointed. I have never dyno'd my car but I can say that it feels like it has more HP and torque now.
