Note:

Check your spark plug wires regularly! Like everything else on your car, spark plug wires need to be checked and require periodic changing. If you want to keep the performance of your engine at the optimal level, we recommend you replace your spark plug wires at the same time you replace your spark plugs. Fouled, damaged, or worn out spark plugs can lead to a variety of engine problems, such as misfires, hard starts, increased emissions, poor fuel economy and reduce acceleration. For most vehicles, you should replace your spark plugs every 30,000 miles.
