In general, it is recommended that the spark plugs in your GMC truck or SUV be replaced every 30,000 to 50,000 miles. Your owner’s manual will have the information you need to find out how often to change spark plugs for your specific GMC model. This guide from the service team at Bell And Bell GMC will fill you in on what you need to know about spark plugs. If you need a new set of GMC spark plugs installed in your vehicle, schedule an appointment at our service center in Little River today!



When Should You Change Spark Plugs? 

Spark plugs are a crucial component in your engine as they transfer the high voltage current from the ignition coil to ignite the fuel in the combustion chamber. Carbon deposits can build up on spark plugs over time, causing issues such as: 

  • Engine misfire
  • Rough idling
  • Poor acceleration
  • High fuel consumption

What Are the Benefits of Changing Your Spark Plugs?

Knowing how often to change spark plugs can help you avoid a hefty repair bill due to the issues listed above. By routinely replacing your GMC spark plugs in accordance with your maintenance schedule you’ll enjoy:

  • Improved fuel economy: Worn out or malfunctioning spark plugs can reduce fuel economy by as much as 30%, so regularly replacing them will help your vehicle to run efficiently at peak performance levels on the roads in and around Myrtle Beach.
  • Consistent combustion system: Spark plugs work to maintain continuous production of combustion, allowing your engine to run smoothly.
  • Less harmful emissions: Replacing your GMC spark plugs can help increase your gas mileage as well as reduce harmful tailpipe emissions.
