I find the idea of shop vac hose running from the lower vent intriguing. As long as it didn't get in the way of anything (off to the side) I'm kind of tempted to mess with it a bit.

One thing I feel unsure about is "lag"; shop vac tubing would probably crack over time from flexing so much under hard accelleration. Maybe that's just a figment of my imagination though.

In reality, there's reasons a shop vac tube isnt OEM for cold air intakes on car engines
