When do I change the spark plugs in my vehicle? If you’ve been confused about how often to change spark plugs, you aren’t alone. It’s an important component of any maintenance schedule, but because the answer can vary between vehicles, many car owners are left without a clear answer. The average driver only needs to replace their spark plugs every 30,000 to 80,000 miles, so how do you know when it’s time? Read on with Hendrick Cadillac Southpoint for more information, courtesy of our service professionals

When Do I Need to Change My Spark Plugs? 

When you go to start your vehicle up in Raleigh or Chapel Hill, the spark plugs go to work as one of your ignition components, moving high voltage current away from the ignition coil to ignite the combustion chamber. If your spark plugs are failing, here’s how you’ll know:

  • Difficulty starting the vehicle or total failure to start
  • Engine misfire 
  • Rough idle
  • Rough-running engine 
  • Poor acceleration 
  • Increased fuel consumption

What Are the Advantages of New Spark Plugs? 

With more insight into how often to change spark plugs, why change your spark plugs in the first place? It probably goes without saying that you want to avoid the issues laid out above; changing the spark plugs at the recommended time will help ensure that. Other key benefits of changing your spark plugs include: 

  • Sustained fuel-efficiency: Failing spark plugs can take a serious toll on your fuel economy, reducing it by up to 30%! Maintain your efficiency on Cary roads and highways by getting new spark plugs when your car needs them. 
  • Quality combustion system: The continuous production of combustion your vehicle needs to keep the ignition system running properly is better facilitated with good spark plugs.
  • Dependable vehicle startups: Replacing your spark plugs will help your car get a clean startup every time.
  • Less harmful emissions: In addition to bettering your fuel economy, you can also improve your vehicle’s emissions with new spark plugs.
