The NGK BKR7E-11 copper plugs are the ones that are two-steps colder. You should be posting this in the Supercharged/Nitrous Forum or whatever its called.

NGK only. If you are using N2O and SC then you should know that.

BKR7E-11 copper 2 step colder
BKR7EIX-11 iridium 2 step colder

Iridium is more expensive but provides a better spark for your uses.
