How Often to Change Spark Plugs

If you’re like lots of other car owners in Matthews and Waxhaw, maybe you’ve wondered how often to change spark plugs but still aren’t quite sure of the answer. Typically, experts recommend changing the spark plugs every 30,000 miles. However, spark plug replacement intervals can vary between makes and models. The best place to go for a model-specific answer is your owner’s manual, but in the meantime, you can join our service team down below to learn more about spark plugs!

When Do I Change Spark Plugs? How to Tell if Replacement is Needed

Your car’s spark plugs are merely one component of the larger ignition system. They transfer the high voltage current from the ignition coil to ignite the combustion chamber when you start your vehicle. Since they’re needed to successfully start your car, you’ll probably agree with us that the spark plugs are pretty important!

If your answer to “when do I change spark plugs?” is “as soon as possible”, here are some of the warning signs you might notice:

  • Sluggish start or not starting at all
  • Poor engine performance
  • Engine misfires
  • Inhibited acceleration
  • Elevated fuel consumption
  • Rough idling

What Are the Benefits of Replacing Spark Plugs?

Thankfully, how often we need to change spark plugs is relatively infrequent compared to other routine maintenance. When you’ve put enough miles on your vehicle that it needs new spark plugs, there are several benefits to replacing them:

  • Better MPG – What many Weddington drivers don’t realize is that worn out spark plugs can lower their fuel economy by a whopping 30%! Replace the spark plugs when needed, and you’ll never have to fret about fueling up too often.
  • Dependable combustion system – You need your car’s ignition system to run smoothly, and functioning spark plugs are a necessary part of achieving that.
  • Reliable starts – New spark plugs lend themselves to a smoothly operating ignition system, which in turn gives you a reliable start every time you turn the key or push the button.
  • Improved emissions – In addition to improving your fuel economy, new spark plugs can also keep your vehicle’s emissions as clean as possible.
