Spark plugs are critical components of an internal combustion engine, responsible for igniting the air/fuel mixture within the cylinders. A spark plug generates a precisely timed electrical spark that initiates combustion, driving the piston and ultimately powering the vehicle. The longevity of these components is finite and periodic renewal is a standard maintenance procedure.
Regular spark plug replacement maintains optimal engine performance, fuel efficiency, and reduces the risk of engine misfires or damage to other engine parts. Historically, spark plug technology has evolved significantly, leading to extended lifespan and improved reliability. However, consistent replacement, as per manufacturer guidelines, remains essential for preventative maintenance.
