Understanding Spark Plugs
What Are Spark Plugs?
Spark plugs are small, but vital, components of your car’s engine. They serve the essential function of igniting the air-fuel mixture within the engine’s cylinders. This ignition creates a controlled explosion that generates the power needed to propel your vehicle. Each spark plug delivers an electric spark that initiates this combustion process, ensuring that your engine runs smoothly and efficiently. Without properly functioning spark plugs, your car may experience issues such as engine misfires, reduced fuel efficiency, and poor overall performance.
