An example would be iridium spark plugs, the centre electrode is not the same as the standard plug with a soft core, the iridium core is far more resilient to the erosion of the high voltage spark, standard plugs use a soft metal core that will erode away rather quickly, say 20,000Kms with iridium plugs rated to 100,000km's

Plug charts will offer a variety of plugs from standard to long life, long life are better value in my opinion.
