When it comes to maintaining your vehicle, there are many tasks that can seem daunting, especially if you’re not familiar with the inner workings of your car. One of the most important, yet often overlooked, maintenance tasks is changing the spark plugs. Spark plugs play a crucial role in the engine’s performance, and neglecting to change them can lead to decreased fuel efficiency, rough idling, and even engine damage.

Changing spark plugs is a simple and relatively inexpensive way to ensure your engine is running at its best.
