Which is better a resistor or non resistor spark plug?
Using a non resistor spark plug on a system designed for resistor plugs will weaken your spark and therefore negatively affect power output of the engine. ... Using a resistor spark plug on and ignition system designed for non-resistor spark plugs also negatively affects power output.

resistors in a spark plug decrease the amount of current that's allowed to flow to the electrode. By using a non resistor plug will significantly increase the voltage and current across the ground and Electrode there for creating a much hotter more intense Spark. BUT too much voltage may harm the electronic system or even the ECU, on the event of voltage leak.
