Iridium Plugs

[wetwilley99]

Is it alright to run them in a 97?

shure can but why not just the oem copper? you wont gain anything but maybe a better throttle response(maybe), I prefer the copper, they are a tougher plug than iridium from fouling/ plus copper is better plug for high hp cars

Chanps RC12ECCs, best plug to run in our cars, period.

I kind of disagree, especially for street use (IMHO). I ran IR plugs in my Gen 3 and felt a noticeable improvement in response (seat of the pants). I plan to put them in my Gen 4.
