when i had a subaru, i ran one step colder iridium plugs at 30+psi on my gt35r. as far as i can tell iridium's last longer but cost alot more.
you dont gap iridium's, they are pre gapped and should never be re gapped.

When I got my Soarer they came with iridium plugs from Japan so I replaced them with the NGK iridium plugs. You can go and ask for 2jz iridium plugs at any parts store. You don't have to gap them unless you're running a crap load of boost.. They come pre-gapped to .028 or .030 I think, so you should be fine. They last a long time if you don't run them super rich or they will foul a bit..
