The spark plug gap is a simple form of a voltage regulator.  You cannot 
produce any more voltage than that required to jump the gap.  So your 
45,000 volt coil is useless at the stock spark plug gap, you are not 
using any more voltage than you were with your stock coil.  The only 
advantage with the extra voltage and not widening the spark plug gap is 
you can extend your service life, as the spark plug wears and the gap 
widens, you still have enough voltage to run it, but a .043 gap from a 
worn plug is not the same as a .043 gap from a new plug.  The new plug 
has sharp edges, which allows ions to flow from, which is believed to 
create greater combustion efficiency.  This is where multiple electrode 
plugs are useful.
