The rebuilt 100-6 came with new NGK BP6ES spark plugs installed. They seem to work fine, but some say that a resistor type plug (NGK BR6ES or equivalent) is better.
Can anyone tell me what actual difference switching from a non-resistor plug to a resistor type plug may make? Is it better for power and for the engine health?
As a related question, it seems that many people now prefer Champion plugs over the NGK plugs. If so, what advantage will one likely see by switching to Champions, and which Champion plug would work best for this engine?
Thanks for any help with this.
Edit: I suppose it makes a difference if the plug wires are resistor wires or not - not sure what is on the car. Probably time to get out the multi-meter?
