IMHO that's just looking for detonation.
ONLY reason to run hotter plugs is if your current plugs are fouling. Causes of fouling could be excessive fuel and short runs that don't warm up the engine or lots of low speed driving.
Saab factory recommends COLDER plugs for extended high speed driving. QED.
Putting hotter range plugs into a modded engine with increased boost, etc., is likely to cause or increase detonation...the APC may or may not correct for this if it hasn't been overridden, but detonation WILL put a hole in a piston.
