What Are Spark Plugs and Why Are They Important?
Spark plugs are one of the most important components of your vehicle’s ignition system. They serve a critical function by igniting the air/fuel mixture within the engine’s combustion chamber. This spark initiates the combustion process, which powers the engine. Without spark plugs, your engine would not run.
Over time, spark plugs wear out due to constant use, which can lead to a variety of engine issues. A worn-out spark plug can cause poor fuel efficiency, engine misfires, or difficulty starting your vehicle. Regularly replacing spark plugs is essential to keep your vehicle operating efficiently and smoothly.
