Do I have to use non-resistor spark plugs together with HotWires, and what will happen if I use resistor spark plugs?
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. Why do car manufacturers recommend resistor spark plugs, aren’t they needed to suppress interference (EMI) with my radio or engine management system? There are many reasons for OEM’s to use resistor plugs. One reasons is actually emissions. Since the resistor is a obstacle it forces the spark voltage to be higher, assuring combustion in a lean mixture. Also resistor plugs are MUCH cheaper to produce. You will never find resistor plugs in serious race cars, yet these cars use some of the most sophisticated engine management systems and data acquisition systems. But these cars have no EMI problem. Why? Because the resistor in the plug is NOT needed to suppress EMI. The spark happens inside the combustion chamber where he is completely shielded by the metal cylinder head. No EMI can escape th
