SC'd LS2 VXR8 what plugs

[impVXR888]

As title, what spark plugs do people use in their charged LS2's?

Please don't just say LS9 plugs, as I'm after a part number ideally.

For example in my Astra I use NGK-BKR9EIX iridium plugs.

I'm getting a slight mis-fire if I put my foot down below 2000rpm, but it's fine above that, so thought I'd start with changing the plugs.

Thanks

I was looking at the NGK TR7IX plugs that's all, seem to recommended on some of the American Vette forums for charged vehicles.

Just wondered if anyone had used any other plugs than the LS9 AC Delco's?

But I guess if they work well, then no reason to change.
