      Iridium spark plugs will not wear out. They might become fouled due to
      other issues. They should be left alone as long as there is no misfire.
      With still plugs the gap would widen with use until the spark can no
      longer jump. Then the high voltage starts to stress the ignition wires
      or coil pack.
      That does not happen with iridium or platinum.

      The reason the protocol call for 60K change is to keep shops busy while
      the lawyers celebrate by keeping the car makers free of claims if a plug
      should fail and the owner was not instructed to change them periodically.
