Which Spark Plug Is Better – Resistor Or Non-Resistor?
Everyone’s answer is different. Non-resistor spark plugs may not be beneficial to certain people. The voltage generated by today’s ignition coils is more than adequate.
You’re causing more radio interference by using a non-resistor plug, according to the experts (EMI). That’s because using a non-resistor plug raises the voltage and current over the ground substantially.
Remove the resistor from the plug and you’ll see an even greater gain in power. A non-resistor spark will raise the voltage at the spark plug’s terminals.
Resistor Vs Non Resistor Spark Plugs: Updated 2023
Many motorists wonder whether resistor or non-resistor spark plugs are preferable. Resistor-type spark plugs have an inbuilt resistor that reduces the

I still stand by my recommendation of resistor plug IF your running any wireless electronic equipment on your bike as the non-resistor plugs will interfere with their function.
If running your electronics on your bike via wired versions, than the resistor plug is not necessary.
I have not noticed any gain in power or lack thereof by using either one...That is known in racing circles, especially with race cars, to be a factor but not so much at all in these basic little China Girls motors that most of us are using.
