In an email message earlier it was mentioned using a K&N washable
filter.  I
run them on my off-road VW's with good success.  The one thing I add
is one
of the K&N pre-filters.  If the engine starts choking down due to
dust, you
can pull it and knock most of the dust off in clumps and continue on.
 With
just the filter, that's not an option.

Subject: Air intake

I've a Subi engine in my Vanagon and on recent trips in VERY dusty
conditions found the air filter collected too much dust.  At present
it is a
cone type with a cleanable paper filter.

Has anyone put their filter up through the panelwork that runs up the
corner
of the van to the air vent?  I can envisage some sort of a flexible
hose,
but I have trouble knowing what sort of filter to put up there,
inside the
vent, so that it doesn't change the appearance of the van.

An alternative might be to shroud the existing filter somehow so that
all
its air comes from up in that cavity, but the last thing I want to do
is
reduce the air flow into the intake.

Any comments anyone?
