[AT] OFF TOPIC - 7.3 L Diesel Air Filter - 2003 Ford F250

[Ronald L. Cook]

See?  If the intake is collecting dirt, so is the engine.  Rest MY case. 
  I actually found this exact same thing on my son's GMC Jimmy with the 
K&N filter installed.  And...it isn't much of a truck.  Of course the 
K&N went in the trash and an OEM paper filter went back in the vehicle. 
  We had quite a discussion about this same thing last winter sometime. 
  I will now leave it alone.
