Yes. I never saw where they are "hotter" but I know that the material is more heat resistant and durable under hotter conditions. The temp varies by which plug you get.

It is recommended to run a colder plug if turbo'd to get rid of pre ignition.
An iridium IX plug will more than likely trigger pre ignition high rpms.

The one that he is showing, the iridium plug from speedcorps, is a colder plug... Look at the heat range (7, colder than stock)...
