Resistor type spark plugs?

[thefastestz]

What is the differance between the resistor type spark plug and the non-resistor type? I went to the parts store and they gave me resistor type spark plugs cause they were all they had, I thought that my car called for non-resistor type. I told the parts guy and he told me they fit and will work better. I do not believe him. I didn't buy them, but does it matter?

I dont think it makes any difference in performance. Resister pluggs are for radio clearity. I have never seen any datia showing any loss of power using either .
