Going to be putting a tick performancce cam in an 07 and I just wanted to know the best plug to go with since we are doing headers to might as well swap them all out at once.

Is the TR5 the best option or should I got with the TR6?

Is the Iridium plugs worth the extra money?

Z06 iridium plugs. Do a search, there are a couple of posts about this.

I believe there are a few opposing opinions on this matter. I'm going to run copper tr6's in mine, and if I get a service charging system issue I'll go with 6ix irridiums.

Unless you don't trust your tuner, in which case they shouldn't be your tuner, I'd go with the plug and gap they recommend.
