What does a spark plug do?
A spark plug creates the spark needed to ignite the fuel and air mixture inside the engine. A good quality spark plug helps your engine start easier, run smoothly, and operate efficiently.
How do I know which spark plug I need?
The correct spark plug depends on your vehicle’s make, model, engine size, and year. Using the manufacturer’s recommended plug is important, as the wrong type can affect performance or cause starting issues.
