Probably a set of NGK TR55 plugs if you like copper plugs and don't mind changing them every 30k or so.

The temperature of a plug means the operating temperature. If you increase the compression ratio (IE turbo, supercharger, nitrous ect.) the engine produces more heat and makes the plug get hotter than normal. If the plug gets hot enough it acts like a glow plug in a diesel and ignites the fuel air mixture before the spark does. This will cause pinging and dead pistons. I run the TR6 plugs gaped at .035.
