hey, i just ordered a pair of these plugs off ebay for 39 shipped and i was wondering if they add any noticeable power. i would like to hear any comments from anyone that has them.

 

i put them on my max and they it seemed to run the same as the old ngk dont know if you are going to get any noticeable diff. out of them but i also have a bad ks that i ahve to replace got a new one today anyone want to put it in for me i buy the beer

 

Why are you putting iridiums on a N/A car? What a waste of $$$.

 

I put the iridiums in my car and didnt notice anything in performance but the car seems to be smoother, maybe because they were new plugs, not neccesarily because they were the iridiums, im not too sure

 

They aren't going to help nor hurt. They are supposedly better for people running high output boosted applications.

 

ngk plats are better for NA, imo
