Maintaining your vehicle is essential, and one of the key components you shouldn’t overlook is the spark plug. Wondering about the spark plug replacement cost? You’re not alone.

What Is a Spark Plug and Why Does It Matter?
Before diving into costs, let’s talk about what a spark plug does. A spark plug is a small but mighty part of your car’s engine. Its job?

In short, it’s a tiny hero you can’t afford to neglect.
