Original Mopar Spark Plugs

What Do Mopar Spark Plugs Do?

Your engine is a complex machine with many working parts. Spark plugs play a major role in your engine's functionality- but what do they do? They ignite the mixture of fuel and air in your engine. Spark plugs fit into the cylinder head and "spark" to ignite the fuel.

When Should I Replace My Spark Plugs?

Like other parts of your car, eventually you're going to have to replace your spark plugs. Here are some of the symptoms that indicate it's time for a replacement:

• You're having a hard time starting your car, truck, or SUV
• Your car is getting lower fuel economy than normal
• Your car is having issues accelerating
• The Check Engine light is on
• Experiencing engine misfires

Broken or worn-out spark plugs can damage your engine's cylinders. If you notice any of the signs listed above, you are going to want to perform an inspection.
