Best Practices
  • To prevent ignition misfires and Check Engine Light problems, we recommend using only high-quality spark plugs, and preferably spark plugs from the OEM.

  • 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 the vehicle manufacturer.

Common Symptoms
  • Failing spark plugs can cause the engine to run rough and misfire, which can trigger the Check Engine Light. Continuing to drive under these conditions can damage the catalytic converter.
