Who runs copper plugs?
I'm contemplating going with copper plugs (1-step colder) for my Vortech setup, and just changing them every 10k miles. i've read through a lot of threads regarding plugs. From what I've gathered, platinum is not recommended for FI but rather Iridium plugs are better suited. Copper plugs will work, but will need replacing sooner.

I run coppers on TT VQ. copper is a better conductor than iridium.
NGK LFR6A-11 for copper (1 heat range colder)
NGK LFR6AIX-11 for iridiums.
I have found the coppers cheapest on www.boat.net for $4.xx per plug and cheap shipping too.

But the large cooper electrode takes far more energy to fire, vs. a very fine point of iridium. And all things being equal, Iridiums will last much longer. That said, I don't think you'd have any problems running copper plugs, but as mentioned, why take a chance on a part that is relatively inexpensive to begin with.
