Wondering How Often to Change Spark Plugs?

Spark plugs in a row

A common question we hear at Alexandria Volkswagen is, “When do I change spark plugs?” In most cases, automotive experts usually recommend that drivers replace spark plugs every 30,000 miles, however, this interval can vary based on your particular make and model. That is why it is recommended that you consult your owner’s manual for recommendations from the automaker. Alexandria Volkswagen further explains how often to change spark plugs as well as the signs your spark plugs need to be replaced.

When Do I Change Spark Plugs?

Spark plugs function by moving the high voltage current from the ignition coil to ignite the combustion chamber as soon as you start your vehicle. When your spark plugs are not performing as they should, you may notice one or more of the following issues:

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

Why Should You Change Your Spark Plugs?

Regularly changing your spark plugs has additional benefits other than preventing the issues mentioned previously.

  • Improved fuel economy – Having a worn out spark plug can reduce your fuel economy by as much as 30%. If you want your vehicle to run as efficiently as possible on the roads of Arlington, regularly changing your spark plugs can help with that.
