The engine of your vehicle is a complex machine that relies on various components to function efficiently. One of the most critical components is the spark plug, which plays a vital role in igniting the fuel-air mixture inside the engine’s cylinders. Over time, spark plugs can wear out, leading to decreased engine performance, reduced fuel efficiency, and even engine damage. Therefore, it is essential to know how often you need to change the spark plugs to maintain your vehicle’s health and longevity.
Spark plugs are relatively inexpensive compared to other engine components, but neglecting to replace them can lead to costly repairs down the road. In this article, we will delve into the world of spark plugs, discussing their importance, types, and lifespan. We will also provide guidance on how often to change spark plugs, depending on various factors such as vehicle type, driving conditions, and manufacturer recommendations.
