Some Ladue drivers often wonder how often they need to change the spark plugs in their BMW vehicle. While experts generally recommend replacing them every 30,000 miles, it will vary depending on your specific model. Refer to your owner’s manual for specific information. Find out more about when to replace these spark plugs below, then contact the BMW of West St Louis service center if you need help with your spark plugs.

When Do I Change Spark Plugs?

Your spark plugs are one of your ignition components that work by moving the high voltage current from the ignition coil to ignite the combustion chamber once you start your vehicle. If the spark plugs are not functioning correctly, you will start seeing problems in your vehicle’s performance such as:

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

Benefits of Changing Your Spark Plugs

On top of avoiding major issues like those mentioned above, there are added benefits that come from regularly changing your bad spark plugs. Learn about the benefits of replacing your spark plugs as part of the preventative maintenance schedule for your new BMW vehicle:

  • Improved fuel economy – Having a worn out spark plug can reduce your fuel economy by as much as 30%, and replacing it can help gain that back.
  • Consistent combustion system – Spark plugs allow for the constant production of combustion that leaves your vehicle’s system running the way that it should.
  • Your Vehicle Starts Smoothly – Replace your spark plug, and when you turn the key in the ignition, you can feel your vehicle start effortlessly.
