Where to buy Denso Iridium?

I've seen this posted months ago and if anyone has the link please re-post. I've recently added a few bolt-ons and would prefer to go the Denso plug route - IT20's specifically. The local Autozone carries them but only in the stock heat range (IT16) and are unable to order one heat range colder that I'd like to use.
Thanks in advance...

I got mine from Outrageous Performance and they will pre gap them if you want.
