How Often to Change Your Spark Plugs

Spark plugs are one of the components in the ignition system that works by moving the high voltage current from the ignition coil to ignite the combustion chamber as soon as the vehicle is started. If the spark plugs are not functioning correctly, you will begin to see issues in your vehicle’s performance:

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

On top of avoiding the issues above, there are other benefits that come from checking your spark plugs regularly as part of the preventative maintenance schedule for your new Chevrolet vehicle:

• Consistent combustion system – Spark plugs allow for the constant production of combustion and leave your vehicle’s system running the way it should.
• Improved fuel economy – Having a worn out spark plug can decrease your fuel economy by as much as 30%, and replacing it can help get it back.
• Less harmful emissions – Replacing your vehicle’s spark plugs can not only help increase your gas mileage, but it can also improve your emissions.
• Your vehicle starts smoothly – Replace your spark plug, and when you turn the key in the ignition, you can feel your vehicle start effortlessly.
