Do Spark Plugs Affect Engine Power?

[DawsonLynn]

Spark plugs affect engine power and fuel consumption. The strength of the spark and the timing of ignition directly determine the combustion results. High-quality spark plugs provide stable performance at both high and low speeds, produce strong electric sparks, and ensure complete combustion of the air-fuel mixture, resulting in stronger power output and better fuel efficiency. The electrodes of the spark plug continuously generate sparks to ignite the air-fuel mixture in the cylinder. Other components of the ignition system produce precisely timed high-voltage electrical pulses, creating sparks and explosions that provide the energy required for engine power output. Spark plugs are devices that ignite the air-fuel mixture entering the engine combustion chamber, operating under extreme conditions of high temperature and high pressure, making them one of the wear-prone components in gasoline engines.
