Waaay, ditto. My TIICO install was initially done without this snorkel in
the left "D" pillar and resulted in really big intake resonance in the cabin
under acceleration at 3-4K. It is now completely gone due to this addition.
I imagine the wasserboxer would also sound this way without the snorkel on
the opposite side, but I don't know.

Incidentally, the air intake snorkel makes a *huge* difference in noise
level on the diesels.  Make sure yours is assembled.  Without the snorkel
the intake noise on mine dominated the engine sound so much that fixing
two major exhaust leaks made no noticable difference.
