Types of Spark Plugs
Spark plugs may seem simple but they are few differences that makes them different from each other. Visually, the look all the same but it is the inside construction that is different.

They aren’t completely trash but since there are better alternatives that people can get at almost the same price point. But if you own a modern car then you might not be able to use copper plugs at all.
Platinum Spark Plugs
