When Do I Change Spark Plugs? 

Waterford drivers wondering how often to change their spark plugs have the general answer, but since there’s so much room for variation, it’s also good to know what the signs are that your spark plugs are malfunctioning. Here are the most common signs: 

  • Slow or no start
  • Engine misfire
  • Rough idling
  • Poor acceleration
  • Engine is running rough
  • High fuel consumption

Benefits of Changing Your Spark Plugs

In addition to preventing all the issues above, you can expect the following additional benefits when you stay on top of your spark plug intervals:

  • Improved fuel economy – Old spark plugs can diminish your fuel economy by as much as 30%. Replace yours, and you’ll more than absorb the cost in savings at the pump. 
  • Consistent combustion system – Fresh spark plugs make it easier for your engine to continuously combust, meaning that you’ll enjoy smoother acceleration.
