You may be able to find what you need.
NGK TR6IX would be the Iridium NGK model of the TR6.
I have heard Duttweiler became a fan of them after some testing.

Are the NGK iridiums cheaper than the Densos? i have NGK TR6s in my car but I'm really curious about the iridiums.

<strong> FWIW, we've seen absolutely ZERO benefit (on the street or on the dyno) from switching a properly tuned car over from NGK TR6's to iridiums in several applications.

On an LS1 - probably not necessary, as their ignition system is damn good. Plus I have yet to see an LS1 that runs high boost(high boost being relative - in my turbo setups, I'll do 20-25psi, and you find out if your ignition is up to par pretty quick). The ignition is pretty poor on the turbo stuff I've done (in comparison to the LS1 coil near plug setup), and anything you can do to increase energy at the plug is good. In those situations, I think the Iridiums would be a good choice (if you can afford it <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" /> ).

TR6's at .028, and it only takes .1 A/F change to cause misfire.

2) N/A 4.6L 2V Mustang
3) Supercharged 4.6L 4V Mustang, 9psi
Same results every time, no different than a fresh set of NGK's.
