Having more oxygen in cooler more condense air is actually an incidental reason for the intercooler.  The desiel engine is a classic heat engine and efficiency of the ideal heat engine is proportional (not linearly though) to the temperature difference between the input side and the output side.  Thus by keeping the incoming "energy source" cooler we can get more "work" out of the engine ,ie., a more efficient engine.  This is enthalpy (not entropy.)

Hi Ken....
  Most intercoolers I've seen in 18yrs of racing have been after the
turbo...  point being to cool the intake charge after it's been heated by
being compressed...  I do agree with you that it has nothing to do with
turbo longevity though...  (please don't hate me Ken or Chris...  :)
