I know what hot/cold plugs are.  Was asking could we use a hotter plug.  Guess not.

Are High Energy, CD, MSD pretty much the same thing?  Behave the same way regarding being foul resistant?

So if we all converted to MSD ignition would SAG go away? What are we waiting for? ... Jim S.

The advantage of the MSD is that at low RPM, the plug will be hit up to 40 additional times in each cycle. So low tip temperatures at idle are less likely to cause fouling. The MSD is a capaciter discharge system. It applies 350 volts to the coil primary windings, and some coils will fail in short order (probably those with internal resisters to overheat). They provide a list of coils that work just fine with that system.
 
In the past 10 years I have not seen a Mazda race car without a pair of MSD ignition boxes.
