Spark Plug Replacement Service and Cost

Best Practices

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

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 Cadillac.

Common Symptoms

Failing spark plugs can cause the Cadillac XTS's engine to run rough and misfire, which can trigger the Check Engine Light. Continuing to drive under these conditions can damage the catalytic converter.
