resistor versus non-resistor spark plugs

[stackz]

which would you get if both are available and why?

listing for my engine shows a resistor plug and a regular plug. I was just going to get the regular plugs but now I'm kinda curious

Re: resistor versus non-resistor spark plugs

Resistor plugs are normally used to minimize radio interference from the ign system. Some motors need special spark plugs with Q-supressors to work properly. What motor are we discussing?
