Hey, dude. I don't recommend you to put those iridiums... Life of the plugs are much shorter than that of platinums... espetially you got upgraded ignition systems like MSDs, low resistance wires, etc., you may need to change them so oftenly. It will give you slightly better performance than platinums though...:doubt:

although platinums don't conduct as well as their copper counterparts, i still seem to like the idea of platinums too.

It seems that a lot of Cobra owners are hardcore with copper plugs. They won't last as long as platinums, but WILL conduct better.

I agree though, don't waste you're money on Iridiums...cause the bottom line is simple...

plugs DONT make power - ENGINES do!

I run the denso iridums in my car.The it22's gapped at .040. but i must agree they are expensive.I tried the ngks tr6's and lost power on the dyno so i must disagree with plugs dont make power at least on my mods. I am thinking about switching plugs as well due to the $$$ involved in denso's 13-15 bucks a piece lol. And i drive my car way to much to be changing all the time. Once agian this is just my .02 Travis
