AEM’s patented Air Bypass Valve virtually eliminates the chance of hydro-lock in the event the filter of your AEM Cold Air induction system becomes submerged in water. On most systems, the valve installs along the upper portion of the inlet pipe and shuts down induction at the filter when it becomes submerged, rerouting air through its external diaphragm to keep water out and air flowing in. Check with your dealer or call AEM for more information on air bypass valve installation locations.

The AEM Air Bypass valve can only be used with CARB (California Air Resources Board) -Exempted Advanced Engine Management, Inc Cold Air Systems. Only applications listed under CARB E.O. # D-392-22 have exemption. The AEM Air Bypass Valve is NOT for use on forced induction vehicles.
