If you want to keep your vehicle running smoothly, routine automotive maintenance is a must. This includes changing spark plugs at the proper interval, but how often do you change spark plugs?

There may also be different recommendations from the automaker, which can be found in your owner’s manual. Learn more about when to change spark plugs and why this task is necessary with Greenway Nissan of Brunswick. 

When Do I Change Spark Plugs? 

What is the purpose of spark plugs? These tiny components are part of the ignition system, and they work by moving the high voltage current from the ignition coil to ignite the combustion chamber when you start the vehicle. You may notice a couple of warning signs if your spark plugs are not functioning properly. These signals can include:

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

Why Do I Need to Change Spark Plugs? 

Not only can changing your spark plugs prevent the issues mentioned above, there are also additional benefits of keeping up with this simple task.

  • Improved fuel economy – Having a worn out spark plug can reduce your fuel economy by as much as 30%. Spend less time and money at the pump with properly functioning spark plugs. 
  • Consistent combustion system – Spark plugs allow for the continuous production of combustion and allow your vehicle to perform as the automaker intended. 
  • Your Vehicle Starts Smoothly – When your spark plugs are performing as they should, your vehicle will start effortlessly. 
  • Less harmful emissions – Replacing your vehicle’s spark plugs can help your vehicle run as efficiently as possible and also improve your emissions.
