Platinum/Iridium Spark Plug

Platinum/Iridium Spark Plug

Your spark plugs are the source of sparks that ignite an air/fuel mixture during the combustion process. Platinum/iridium spark plugs are a more efficient type of spark plugs used in modern engines. Thanks to the use of harder metals on the electrodes, platinum/iridium spark plugs last up to 100000 miles and even longer.

When should I replace my platinum/iridium spark plugs?

  • Your check engine light is on or blinks
  • Rough idling
  • Misfiring and abnormal engine noise

  • Rough idling and misfiring can be caused by bad spark plugs. In most cases, the check engine light will also come on. 
  • Some engines come with two spark plugs per cylinder. The number of electrodes per spark plug can also vary from one to four.
  • Replacing spark plugs is usually a simple task, except for some late model cars.
  • You should use only high-quality spark plugs recommended by the manufacturer, since poor spark plugs can cause ignition problems.
  • Not all spark plugs are the same. They have different ratings. Pay attention to this when purchasing replacement spark plugs.
  • Spark plugs are some of the parts that need to be replaced at the mileage specified by the manufacturer even if they seem to be in perfect condition.
  • You should follow the manufacturer’s replacement instructions when changing your spark plugs. Aluminum cylinder heads can get damaged if you ignore the recommendations.
