Autolite Copper plugs ok?

Iridium is a type of super dense material. Part of the Plantinum family on the element table. So high voltage and heat should not be an issue. This why the long warranty life of these plugs?
Here is a full explantion of what Iridium is from wikipedia:
http://en.wikipedia.org/wiki/Iridium
The site says this stuff is made for high temps. Highly durable material.
Hydra,
It may be possible that Iridium may give you better performance if not at least much longer life than the regular plugs when paired with your MSD ignition?
Here is an except notes from wiki:
Iridium (pronounced /ɪˈrɪdiəm/) is the chemical element with atomic number 77, and is represented by the symbol Ir. A very hard, brittle, silvery-white transition metal of the platinum family, iridium is the second densest element and is the most corrosion-resistant metal, even at temperatures as high as 2000 °C
Its resistance to arc erosion makes iridium alloys ideal for electrical contacts for spark plugs.[54][55]

Sounds good enough to try. I'll do it on the next change out but I just did it Oct. 1st so it will have to wait.
The only thing I didn't like was the fact they're "brittle". I know you really like them and so has everyone else. I accually sounds like it could deal with the added heat I have and want. I'm gettin itchy.

Hydra,
The fact the iridium can be brittle is only true in its purest form I assume. But when mixed in with other metals, it becomes a super strong durable alloy. If you read wiki, Iridium is super rare, so I would doubt the tip of the spark plug is pure iridium. Problaby the tip is made of a super strong metal mixed with Iridium to make that tip super durable. I think Iridium is many times more expensive than plantinum if you have a solid bullion of it.

Kensai,
what's the code number for the Champion Iridiums that you installed?
I also have a 2000 5.9L R/T, about 154K miles, no engine mods. It starts right up, hot or cold, after sitting for a minute, or a week or two. Plugs were last replaced a long time ago, I think with platinums of some kind, but I don't remember exactly what. Wires, cap, and rotor are Mopar replacement.
Thanks,
- Roger

OK, I think I got the answer I was looking for. Now we are all just arguing. Basically, noone has had problems with IR plugs, OEM and the TRUCK Plugs. Some people have had problems with copper and some havent. ALOT have had probs with Platinum (for the 4.7) So basically survey says....... go OEM, IR, or TRUCK! Now lets coninue on with our lives and play nice.... lol
