What are the benefits of changing spark plugs?

[Vieira]

Replacing spark plugs can improve vehicle performance, as spark plugs themselves are wear-prone components that require regular replacement. The spark plug is a crucial part of the engine's ignition system, responsible for generating sparks that ignite the air-fuel mixture in the engine. When the mixture burns, it pushes the piston downward, enabling the engine to produce power. If the spark plug fails to ignite, the air-fuel mixture won't combust, and the engine won't function. Over time, the electrode gap in spark plugs widens, reducing ignition efficiency. Additionally, prolonged use leads to carbon buildup on the electrodes, further diminishing the spark plug's ignition capability.
