As far as I can tell, the plugs have had very little effect my Miata.  At 
first, I thought differently (maybe a little more power), but after awhile 
I began to think that it was only wishful thinking.  But they did not 
noticably improve my gas mileage.  In fact, in my Isuzu Trooper, the mileage 
definitely improved when I removed them.
