Here's a test that was done by the Duramax Diesel group. The Nissan folks discovered it.
It will also demonstrate why so little testing is actually done by consumers. It costs a lot of money to run really good tests.

To me the stock 993 has a well designed air filtration system that probably can't be improved on except maybe to make more noise...and thus the perception of more power.
