How Often to Change Spark Plugs

When do I change spark plugs? It’s a question we hear often at the Hendrick Buick GMC Cary service center! Many experts will recommend replacing spark plugs every 30,000 miles, but when it comes to how often you need to change spark plugs, the answer isn’t the same for every vehicle or every driver. Check your owner’s manual to see what the manufacturer recommends, and if you’re still confused about how often to change spark plugs, keep reading.

When Do I Change Spark Plugs? Signs it’s Time for Replacement

The spark plugs are an essential ignition component that ensure you’re able to start your car up every day in Cary and Raleigh. They move high voltage current from the ignition coil to the combustion chamber when you turn your ignition or press the start button. If your spark plugs need to be replaced, you may experience one or more of the following issues:

  • Delayed start or failure to start
  • The engine misfires
  • The engine seems “clunky” when it’s running
  • Your car’s typically smooth idle has been rough and shaky
  • Accelerating on Charlotte roads is a struggle
  • Your vehicle is burning fuel more rapidly

Why Should You Change Your Spark Plugs?

Avoiding the aforementioned issues is reason enough to replace your spark plugs when necessary, but there are more benefits to enjoy when you take care of this essential service. Here are a few more benefits of replacing spark plugs:

  • Consistent fuel economy – Failing spark plugs can reduce fuel efficiency by as much as 30%! Replacing the spark plugs will help maintain excellent fuel economy.
  • Reliable combustion system – Your vehicle needs continuous combustion in order for the ignition system to run properly; spark plug replacement ensures the continuous production of combustion.
  • Seamless startups – Difficulty starting your vehicle before work in the morning is likely the last thing you want to endure. Changing your spark plugs when you need to will ensure a quick, smooth start as soon as you turn the key.
  • Cleaner emissions – In addition to improving your fuel economy, new spark plugs can also help improve your vehicle’s emissions so you can enjoy greener travels in Charlotte.
