How often should I change the spark plugs on my Dodge Dart?
Maintaining your Dodge Dart in peak condition involves keeping up with routine maintenance, including spark plug replacement. Spark plugs play a crucial role in your car's engine performance, fuel efficiency, and overall reliability. But how often should you replace them? Let’s dive into the details to ensure your Dodge Dart runs smoothly for years to come.
Manufacturer Recommendations for Spark Plug Replacement
