The snorkel set-up also allows the air cleaner to get
cleaner air (from up high) than it would if it took
the air from the engine compartment, as the wheels
kick up a lot of dust (on back roads).  No special air
filter, just the filter in the air-cleaner box (try a
good K&N filter).  The 'cyclone' filter acts as a pre
filter for large stuff and water.  Re rivers, the
exhaust will blow water out, but sucking water in the
intake will blow heads as the water will not compact
in the cylindars.  Regular diesels work better in wet
conditions (river crossings) as there is no elect to
the non-existent spark plugs to short out (TDIs may
short out).  That's what I know about this topic.

i realize it has something to do with river crossings
and water not getting into the engine and such, but
why and how
