When Do You Change Spark Plugs?

row of spark plugs

“When do I change spark plugs?” It’s a common question we hear at the Sunset Chevrolet service center. The answer is a pretty wide range: 30,000 to 90,000 miles. It depends on the type of vehicle you drive, the type of spark plugs you’re using, and the amount of wear and tear you put on your ride. As part of routine maintenance, your owner’s manual will have the manufacturer’s recommendations for when to swap your spark plugs out for new ones.

Why Do I Change Spark Plugs?

What is the purpose of spark plugs? Spark plugs are one of your ignition components, and they transfer the high voltage current from the ignition coil to ignite the fuel in the combustion chamber when you start up your vehicle. How will you know if your spark plugs are not operating as the manufacturer intended? You will likely notice issues with the performance of your vehicle. Warning signs may include:

  • Slow or no start

  • Engine misfire

  • Engine is running rough

  • Rough idling

  • Poor acceleration

  • High fuel consumption

Benefits of Changing Your Spark Plugs

Not only will regularly changing your spark plugs help to prevent the issues listed above, there are a few other noteworthy benefits of properly maintaining your spark plugs.

  • Improved fuel economy – Worn-out spark plugs can reduce your fuel economy by as much as 30%.

  • Smooth starts – Your vehicle should start effortlessly, and if it isn’t, it’s time to bring it in for service.

  • Less harmful emissions – Replacing your vehicle’s spark plugs on a regular basis can also help to improve your emissions.
