As I remember from automotive ignition classes the biggest thing new plugs provided were sharp edges to get the spark arc started and the older plugs wore the edges round and misfired. Enter platinum iridium etc. extremely hard materials that did not round off so easily so the sharp edges stayed and plugs lasted100k miles. Now cars started using the waste spark method as bikes have for years they discovered platinum or iridium on both the center electrode AND the ground electrode provided great wear great spark and long lift
