AEM’s patented Air Bypass Valve virtually eliminates the chance of hydro-lock in the event the filter of your AEM intake becomes submerged in water. On most systems, the valve installs along the upper portion of the inlet pipe. It shuts down induction at the filter when it becomes submerged. Air is routed through the bypass valve's external diaphragm to keep water out and air flowing in. Contact AEM customer service for more information on air bypass valve installation locations.

The AEM Air Bypass valve can only be used with CARB -Exempted AEM Cold Air Systems. Only applications listed under CARB E.O. # D-392-22 have exemption.
