I would never have guessed, but the snorkel makes a very noticeable
power difference on the diesel vans.  In my (former) 1983 ASI camper,
the snorkel made about a 5 MPH difference in top speed at full throttle
in high gear.  VW must have paid some attention to tuning the system.  I
couldn't say if that would also apply to the gas models.
