Abstract
A vehicle includes an internal combustion engine and an air induction system configured to provide intake air to the internal combustion engine. The air induction system includes an intake port, an air box coupled to the intake port and having a wet side air box and a dry side air box, at least one sensor disposed within the air box and configured to detect a presence or level of liquid within the air box, and a watertight door disposed within the air box and configured to move between an open position that allows air to pass through the air box dry side, and a closed position that facilitates preventing liquid from passing into the air box dry side.
