Hey I was thinking about getting some Iridium plugs for my 02 z28 with minimal mods. What do you guys think? is Iridium to much? Should I go with Double Platinum??? what else should I get to complete the plugs?

 

They are a waist, they won't give you more power at all, the only advantage is that they last longer. As a side note DO NOT ever use irridum plugs if you have a power adder.

 

Whats a power adder? and thanks for the advice, I definitely appreciate it. What kind of spark plugs would you recommend if I wanted to change mine out? Is it even worth changing them all out on an ls1 with minimal odds? If not, when is it?

 

Change them when they are worn out or you go with a power adder (nitrous, blower, turbo). I use NGK TR6 plugs in my car.
