I wouldn't get the Bosch filter as it is a rebadged cheapy filter.  Only use
the Mann or Mahle filters for the Vanagon as any other ones will cause a low
oil pressure condition (just enough to have your oil light blink on at stop
lights, etc).
I sell the Mann filters for $4.25 each (US) if you buy 4.  I could ship you
up some via USPS airmail.

Thanks,
