How Often to Change Your Spark Plugs

The electricity used to ignite the air and fuel mixture in your engine is conducted by your spark plugs. They’re a small, inexpensive part that’s easy to overlook. Many of our North Charleston and Mount Pleasant drivers don’t have them replaced until their vehicle is on the fritz. If you’ve been curious as to how often to change your spark plugs, then let the Rick Hendrick Chevrolet parts department answer your question in depth before you have yours inspected. The short answer is that you should have them changed every 30,000 miles, but there’s more to consider. If you have any other automotive questions, consult our FAQ!

When Do I Change Spark Plugs?

Your spark plugs move high voltage from the ignition coil to the combustion chamber to create the controlled explosions that burst your vehicle forward. If your spark plugs are toast, James Island drivers will notice because:

  • The vehicle doesn’t start or struggles to start
  • The engine misfires
  • Your idle sounds choppy
  • You’ve noticed your car is slower to accelerate
  • Your car is burning through gas faster

Benefits of Changing Your Spark Plugs

Now that you have answers to some basic questions like “How often should I change my spark plugs?” and “When do I change spark plugs?”, let’s cover some of the advantages to replacing your spark plugs more regularly.

  • Improved fuel economy – Driving on a fried spark plug can drop your mpg by 30%.
  • Consistent combustion system – Spark plugs allow for the continuous production of combustion and leave your vehicle’s system running as it should be.
  • Your Vehicle Starts Smoothly – Replace your spark plugs regularly and you’ll never have to waste 5 minutes trying to get your car to start again.
  • Less harmful emissions – Replacing your vehicle’s spark plugs is great for the environment because keeping your mpg optimal cuts down on emissions!
