While we do list the 056 115 561G (Mann W719/5 or Mahle OC47), we don't list
it for a Vanagon - just for certain VW car applications.  The one we list
for the watercooled Vanagon is the 056 115 561 (Mann W719/12 or Mahle
OC108). We sell it for $4.29 each if purchased in quantities of 3 or more:

As for the differences, this issue has come up on the list many times
throughout the years. At one point a listmember actually emailed Mahle in
Germany to ask them the difference and whether it really mattered. Here was
Mahle/Germany's reply:

"The main difference between OC 108 and OC 47 is inside these filters. OC
108 has an anti-drain valve at the filter, OC 47 not. When you use OC 47 for
your car (VW Tranporter/Vanagon) than you can get problems when you start
your car. The motor is at this time always to long without oil. OC 108 have
also a better paper quality than OC 47, and the pressure bypass is
different. Please use for your car OC 108, to get no damage at your car or
motor."

So there you have it, right from the horse's mouth.
