As per Adam & vxlaney, I've been happy with NGK bkr7 plugs on LETs in the 300-400bhp range. Bosch F5DPOR have been fine too.

One step colder for my GT3076R engine - NGK bcpr8evx-11 gapped to 0.6mm

If you are looking to go a step colder or hotter, note the heat rating on NGK & Bosch plugs run in opposite directions.
