Spark plugs provide the spark that ignites the mixture of air and gasoline in the cylinders. Each spark plug must be able to reliably produce millions of sparks. Latest-generation spark plugs are manufactured using extremely resistant materials and have an excellent lifespan. However, after several thousands of kilometres, the electrodes where the spark is produced can become covered with dirt or carbon deposits, causing the spark plugs to become less efficient and resulting in increased fuel consumption.
During routine maintenance, a certified NAPA AUTOPRO technician can inspect your spark plugs to determine if they need to be cleaned or replaced.
Each vehicle must be equipped with the type of spark plugs indicated by the manufacturer, depending on the engine characteristics. Your certified NAPA AUTOPRO technician can select the correct spark plugs for your vehicle if they need to be replaced.
