I run spark plugs in my car for 60,000 with no issues. Why is it that everyone recommends replacing auto plugs every year? The only answer I have heard is "They are cheap", and that does not tell me much. Not to mention, that the Iridium plugs I run are not all that cheep.
What about an Aircraft application would necessitate replacing plugs after 150 hours?
