Resistor plugs are being discussed. Technician A says that if the original equipment resistor plugs are replaced with nonresistor plugs, the engine will produce more power at high RPM. Technician B says that if the original equipment resistor plugs are replaced with nonresistor plugs, the engine will run smoother at low RPM. Who is correct?
A)A only
B)B only
C)both A and B
D)neither A nor B

Question

Quizplus · Accepted Answer

Resistor spark plugs are designed to reduce electromagnetic interference with electronic devices such as the car's radio and the ignition system's own electronics. Replacing resistor plugs with nonresistor plugs does not inherently increase engine power at high RPMs or cause the engine to run smoother at low RPMs. The primary function of resistor plugs is to minimize radio frequency interference, not to affect engine performance in the ways described.
