AEM's air bypass valve can eliminate the costly damages that can occur when water is injested. The air bypass valve is created for AEM's cold air induction systems. Should the filter element become submerged in water, the valve springs into action. The valve is installed along the upper portion of the inlet pipe. It will shut down induction at the filter when it becomes submerged and will rerout the air through its external diaphragm to keep water out and keep the air flowing through.
