Does anyone use these? I have stage 2 cai and im wondering what i should get if i should buy these if there any good or any problems. or if i should get the step one colder or what any help would be amazing thanks!

 

search... theres 1000's of posts about plugs, including a active thread right now about plugs

 

I just did a search with the term "iridium" in the 2.0L Performance Tech section and the next post I see is dated from 2010. The other one below are from 2008... so they are not much discussed I guess.

I'd like to know as well...

 

Just get the normal NGK plugs like what ZZP offers, gap to .035 and be happy. 1 or 2 steps colder based on mods. stage 2, is 1 step colder.

 

2 steps colder for a 2.7" pulley I guess...

 

I've used Iridiums for 21k miles with no issues. Saves a few bucks and preforms the same.
