When it comes to maintaining your vehicle, there are several components that play a crucial role in ensuring the smooth operation of your engine. One such component is the spark plug, which is responsible for igniting the fuel-air mixture in the engine’s cylinders. Over time, spark plugs can wear out, leading to decreased engine performance, reduced fuel efficiency, and increased emissions. In this article, we will explore the importance of changing spark plugs, the signs that indicate it’s time for a change, and the process of replacing them.
Why Spark Plugs Are Important
Spark plugs are a critical component of your vehicle’s engine, and their proper functioning is essential for the smooth operation of your vehicle.
