If you're running a higher octane, then you want a HOTTER plug, not colder (or you can just run the proper octane - 87). You always want to be right at the point before detonation.

High octane fuel in the 5SFE is a waste of money. The engine can't take advantage of it (low compression, limited ignition timing).

Thanks In my country 91 OCT is really 83 only so 98 is 93 in real.
