This topic comes up now and then on this list.  In my opinion, I submit that
the stock air
intake system on the Vanagon, and probably most other vehicles, is more than
adequate for the stock engine.
If your heads are stock and your exhaust is stock, I'm sure that opening up
the intake will make no difference in
performance or mileage.  Just remove the air cleaner box or whatever else
you think is restrictive and drive around the block.  Don't mistake more
noise for increased power.

I've never done it, but someone should put the stock air intake system on a
flow bench.  If it's like most other production vehicles it is more than
adequate.  Additionally, flow would only become restrictive at high RPMs,
near redline.  Not an issue for everyday driving.
