with what you've said in mind, i was told, from a friend of mine who used 
to own a rotary, that these spark plugs are also priced proprtional to 
the exponential of the wizardry these things are compared to normal 
plugs. I was told about A$90 each. They'd better last a long time!!

Couldn't the same effect be achieved by cutting the tip of the spark plug 
off a normal plug? It may sound excessive. I know it works at 1 bar, not 
sure at comb. chamber pressures though.
