Have you asked the question, “When do I change spark plugs?” If so, you are not alone. According to some automotive experts, it is a good idea to change your spark plugs every 30,000 miles. However, that interval may be different depending on what make and model you drive. Your owner’s manual should contain recommendations from the manufacturer. Find out how often to change spark plugs, and if it is time to do so, set up an appointment with Bob Moore Auto Group near Oklahoma City. 

When Do I Change Spark Plugs? 

What does a spark plug do? It is an ignition component that sends a high voltage current from the ignition coil to ignite the combustion chamber when you start your car. If you notice any of the warning signs below, it could be an indicator that it is time to change your spark plugs. 

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

Advantages of Changing Your Spark Plugs

Not only does changing your spark plugs help prevent the problems mentioned above, but this maintenance task also has other advantages. Here are a few of the benefits of replacing your spark plugs:

  • Your Vehicle Starts Smoothly – If you want your vehicle to start effortlessly, you will want to be sure all spark plugs are functioning as they should. 
  • Less harmful emissions – Properly working spark plugs help your vehicle run as efficiently as possible and improves your emissions.
