When Do I Change Spark Plugs?

Spark plugs are a part of your vehicle’s ignition components and works by moving the high voltage current from the ignition coil to ignite the combustion chamber when you start up your car. While you should be able to go 30,000 miles before changing your spark plugs, you will want to keep an eye out for some malfunctions that can occur thanks to failing spark plugs. Here are some signs to look out for:

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

Benefits of Changing Your Spark Plugs

While the main benefit of changing your spark plugs obviously comes from the fact that you can avoid the issues we listed above, there are additional benefits to changing your spark plugs before they begin to malfunction. Keep up to date on your vehicle’s maintenance schedule and get these benefits when you change your spark plugs:

  • Consistent combustion system: Spark plugs allow for the continuous production of combustion and leave your vehicle’s system running as it should be.
  • Improved fuel economy: Having a worn spark plug can reduce your fuel economy by as much as 30%, and replacing it can help gain that back.
  • Less harmful emissions: Replacing your vehicle’s spark plugs can not only help increase your gas mileage but also improve your emissions.
  • Your Vehicle Starts Smoothly: If you replace your spark plugs, the next time you start your car, the vehicle should start very smoothly.
