I'm hoping you can address a question on Porsche's spark plug change intervals.  While Porsche dictates the change based on either mileage or time (for example, 30,000 miles or 3 years), I don't see how time/age is a factor in the wear of a spark plug.  If I drive 5,000 miles/year doing longish weekend drives instead of spending an inordinate amount of time idling in traffic,  I don't see how a spark plug deteriorates solely based on time.  Am I missing something?
