So how long do they typically last? Well, standard copper plugs are said to last anywhere from 10,000 to 20,000 miles (16,093 to 32,187 kilometers), while more expensive iridium or platinum spark plugs can last 60,000 miles (96,561 kilometers) or more [source: Spark plugs UK].
Look for plugs made from iridium or platinum for the longest life (copper has the shortest lifespan â generally about 20,000 miles). Oil Leaks: When you pull a spark plug out of the engine, the base should be relatively clean. If there is oil present, it means thereâs a leak. Not only does that mean youâll need to replace a blown seal, but it means your spark plugs will need to be changed more frequently because of contamination.
