Copper plugs are preferred over Irridiums in Supercharged cars. They dissipate heat more quickly.

NGK TR6 gapped at .050" for 2 heatranges colder
Or the Autolite plugs (copper).

Keep the iridiums...they will be fine. I run them in both cars. If you start modding super heavy like Zilla..then start thinking copper.

I spent 2 hours on the phone with NGK (who makes the AC Delco Plugs) and took notes. That'* where the Techinfo article came from, and much of my own knowledge.
A copper plug will last longer and perform better in your cars than an Irridium, and far better than Platinum.
NEVER run Bosch. Bosch ANYthing.
