As you can see in this diagram, the factory intake system also uses the driver's side lower duct to draw intake air, and even the driver's side hood vent is open to incoming air:



I know in stock form this isn't an issue, but I was wondering this for the ess supercharger kit where the air filter is in the driver lower air duct.

Would it be drivable in the winter? what would happen if it was packed with snow for example?
