I thought all these vans came with intakes attached to a snorkel, straight
from the factory. All my Syncros have had this and, as far as I know, so
have all my 2wd vans, although I did not check them all. So the implication
here is that not all come with factory snorkel....or Don, perhaps yours was
missing?
Also, I've brought this up before, but it is not uncommon to have one of
these collapse or semi-collapse, greatly affecting performance.
