Best Practices

To prevent ignition misfires and Check Engine Light problems, we recommend using only high-quality spark plugs, and preferably spark plugs from Mercedes-Benz.

Spark plugs have different ratings and it's important that the correct type are used.

Spark plug terminals wear down over time and can lead to engine misfires. At minimum, they need to be replaced at the mileage specified by Mercedes-Benz.
