Spark Plugs

There are four different types of spark plugs. Copper core plugs are the most inexpensive and work at a higher temperature than the rest. While they are great conductors, they typically only last around 20,000 to 40,000 miles. Iridium plugs work at a lower temperature, and while they aren’t as good at conducting, they do last between 40,000 and 60,000 miles. Platinum plugs last between 40,000 and 80,000 miles and are of better quality than iridium. Finally, for people who want the highest quality spark plugs, there is a double platinum option.
