Man Holding Spark Plug

Changing your spark plugs at regular intervals can help keep your vehicle running smoothly. So you may be wondering, “How often do I change my spark plugs?” Generally, experts recommend replacing them every 30,000 miles, though it can vary depending on your specific model. Refer to your owner’s manual for specific recommendations for your make and model. Learn more about when to replace these spark plugs below, and contact the Dover Honda service center if you need help with your spark plugs.

When Do I Change Spark Plugs?

Your spark plugs are an ignition component that works by moving the high voltage current from the ignition coil to ignite the combustion chamber when you start your vehicle. If there is an issue with your spark plugs, you’ll start to see problems in the performance of your vehicle, such as:

  • Slow or no start
  • Engine misfire
  • Engine is running rough
  • Rough idling
  • Poor acceleration
  • High fuel consumption

Benefits of Changing Your Spark Plugs

Along with avoiding the potential problems above, there are other advantages to changing your spark plugs at the recommended intervals. Find out the benefits of replacing your spark plugs as part of the preventative maintenance schedule for your new Honda vehicle:

  • Improved fuel economy – A worn out spark plug can impair your fuel economy, ultimately decreasing it by as much as 30%, and replacing it can help gain that back.
  • Consistent combustion system – Spark plugs allow for the continuous production of combustion and leave your vehicle’s system running as it should be.
  • Your Vehicle Starts Smoothly – New sparks plugs will allow your vehicle to start effortlessly when you turn the key.
  • Less harmful emissions – Replacing your vehicle’s spark plugs can help improve your emissions.
