Terry,
The purpose in cooling the spark gap is to cut down on
the tendency of a hot gap to spew excess metallic
ions into the gap. That in turn causes the gap to 
conduct too long. Wasting energy.

Many coilers have noticed that when their gaps heat
up the quality of the streamers decreases. Quenching
and all that stuff...
