Peter,
what makes you believe that the low voltage resistance of your spark plugs would actually degrade their performance?
The Champions have a spring inside for contact and I assume that oxide buildup on the metal is responsible for the resistance. In real life, the high voltage sparks should easily bridge that resistance without any significant loss.
I believe only a spark plug tester should be used to judge the quality of a spark plug.
