The best way to ensure that your Acura is always running safely at peak performance levels on Cherry Hill-area roads is to keep up to date with your scheduled maintenance.

So, how often do you need to change spark plugs? Experts recommend that you replace the spark plugs in your vehicle every 30,000 miles, but it can vary depending on your specific model. Your owner’s manual will have the information you need to find out how often to change spark plugs. Learn more about when to change spark plugs in this guide from the service team at Acura Turnersville. If you need a new set of spark plugs or any Acura maintenance or repair service, schedule an appointment at our service center in Turnersville today!

When to Change Spark Plugs

What do spark plugs do? The spark plugs in your car transfer the high voltage current from the ignition coil to ignite the fuel in the combustion chamber. Knowing how often to change spark plugs will keep your engine running smooth and efficiently. If the spark plugs become carbon fouled or aren’t functioning properly, you’ll notice issues such as:

  • Slow or no start
  • Engine misfire
  • Rough idling
  • Poor acceleration
  • High fuel consumption

How often are spark plugs changed? As previously noted, spark plugs should be changed every 30,000 miles, but the type of vehicle you drive and your driving habits may affect how often to change the spark plugs in your car or SUV.

What Are the Benefits of Changing Your Spark Plugs?

How often do you need to change spark plugs to avoid the issues listed above? Again, the rule of thumb is every 30,000 miles. Some of the key benefits of regularly replacing your spark plugs include:

  • Improved fuel economy: Worn out or malfunctioning spark plugs can reduce fuel economy by as much as 30%. Routinely replacing the spark plugs will help your vehicle perform efficiently on the roads in and around Maple Shade.
  • Consistent combustion: Spark plugs maintain continuous production of combustion, which in turn allows your engine to run smoothly.
  • Less harmful emissions: Replacing your Acura spark plugs can not only help increase your gas mileage but also reduce harmful emissions.
