Straight from Nology's website....
Question:
Do I have to use non-resistor spark plugs together with HotWires, and what will happen if I use resistor spark plugs?
Answer:
To take full advantage of the performance gain possible when using HotWires, non-resistor spark plugs are best. If for any reason resistor spark plugs must be used, performance gain is less, because the resistor is impeding the spark, however, performance will still increase.
