Colder plugs will have a shorter ceramic center part, to allow the heat to bleed off into the head quicker, too cold and they may foul, wont keep the carbon burned off (probably not a problem with nitrous) too hot and they can ignite the fuel mixture b4 firing, causing detonation, hotter plugs will have a long, skinny center electrode and ceramic insulator. The middle part number on the plug will change with heat range, ( and some brands, the HIGHER the number, the COLDER the plug, Check b4 you buy, ask to see the catalog, there will be a chart in the back.

Denso Iriduims would come in very many different heat temps. Denso Iriduim is the type, not the temp... Every type of every company's plugs come in different heat temps.

 they should have a name like IK24 or IK 27 where the numper indicates the heat range. higher number=colder plug (my plugs are IK27)

The replacements for stock for the ST are IK16. I do not know about the GT though.
