Background on Vehicle Spark Plugs

Spark plugs are little metal pieces found in the combustion chamber of your engine. They are in charge of sending a little spark between two electrodes to ignite the gasoline in your motor. Did you know that these things go off more than a thousand times for every minute of driving? Over the many miles you drive with your car, the electrodes on a pair of standard-grade spark plugs wear off, and the gap between them enlarges. When this happens, the spark isn't as strong, and the combustion process becomes inefficient. Here are some signs that you need new spark plugs:

  • Engine misfires
  • Rough idling
  • Rattling or loud engine
  • Poor fuel economy
  • Laggy or sluggish acceleration
  • Lit check engine light on the dashboard

Another thing you should know about spark plugs is that there are many different kinds. They vary in material, size, and some last longer than others. You shouldn't just go out on a whim when purchasing spark plugs. Instead, you should always look to your owner's manual as it will suggest which is most suitable for your car. It will also have information on how often you should change your spark plugs.

  • The standard grade is copper core, and these last 12,000 miles (give or take).
  • The single platinum spark plugs, and these last anywhere between 30,000 to 60,000 miles.
  • The double-platinum plugs last about 60,000 to 100,000 miles.
  • The iridium spark plugs typically last more than 100,000 miles. They are the most durable and provide peak performance.
