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

Platinum/iridium spark plug maintenance

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.
