Only the 00 SVT (E1 = 98.5) with it's 10.25 CR is listed as using the colder plugs.
If you have a very aggressive chip program in any SVT you may want to try them, but it is not a neccesity to do so. Even for just timing advance they still may be too cold???
I'd stick with the tried and true sets I previously posted.
Now for any 00 SVT owners reading I have had great success with the colder plugs & running a chip.
