What plugs to run in 98 s/c cobra?

[Roush21]

Hey I need to get some new plugs and Im not sure what kind are in the car now because Ive only driven it for 4500 miles and have yet to change them. I am thinking I should get the NGK TR6 plug? is this right? is it 2 steps colder than stock ? that what I believe someone told me to run and I think that is what Tim from T&J runs. Let me know fella's thanx

I would personally run Iridium plugs on a boosted car. If that is what Tim over at T&Jperfromance suggested, I would go with it.
