How Often to Change Your Spark Plugs

Spark Plug in Front of Black Background

Our service team is asked a lot of questions about routine maintenance. One of the most common is, “When do I change spark plugs?” Whether you own a new or used vehicle, it’s good practice to change them every 30,000 miles — but that distance could vary for your vehicle based on your driving habits. To be certain, it’s always advisable to read your owner’s manual and to talk to certified professionals like the technicians at our service center. For a few quick facts about how often to change spark plugs, read on!



When Do Spark Plugs Need to Be Replaced?

Your car’s ignition can’t operate as intended without working spark plugs. What do spark plugs do, exactly? They carry the ignition coil’s high-voltage current to the combustion chamber, causing it to ignite when you start your car. If the spark plugs are malfunctioning or dead, you’ll notice some warning signs, such as:

  • Engine misfire
  • Engine runs roughly
  • Poor acceleration
  • Decreased fuel-efficiency
  • Slow engine start or startup failure
  • Rough engine idling

What Are the Benefits of Changing Your Spark Plugs?

Changing your spark plugs regularly will help prevent the issues listed above, as well as boost fuel economy, reduce emissions, and more. Here are a few good reasons to ensure your car’s spark plugs are always operating at their best:

  • Greater Fuel Economy – You may not realize it, but a malfunctioning spark plug can cut your car’s fuel-efficiency down by 30% on Westport roads. You won’t reclaim that percentage until you change the bad spark plug.
  • Decreased Emissions – Bad spark plugs not only affect fuel economy, but they also impact the environment. Changing your spark plugs means your car will produce fewer harmful emissions.
  • Smoother Engine Operation – Changing your spark plugs can immediately resolve issues like engine misfiring and rough idling.
  • Seamless Combustion System – If your car’s spark plugs are working as they should, it’s likely the combustion system is also in good shape.
