The spark plug is a crucial component in a vehicle’s engine, responsible for igniting the fuel-air mixture that powers the engine. Over time, spark plugs can wear out and fail to function properly, leading to a range of problems that can affect the performance, efficiency, and longevity of the engine. One of the most critical maintenance tasks for vehicle owners is to replace the spark plugs at the recommended interval, usually every 30,000 to 100,000 miles. However, many drivers neglect this task, leading to a cascade of issues that can be costly to repair. In this article, we will explore the consequences of not changing spark plugs and provide guidance on how to prevent these problems.
