How Often Should You Change Your Spark Plugs?

When Do I Change Spark Plugs?

Your spark plugs are one of your ignition components that work by moving the high voltage current from the ignition coil to ignite the combustion chamber once you start your vehicle. If the spark plugs are not functioning correctly, you will start seeing problems in your vehicle’s performance such as:

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