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.The AEM Air Bypass Valve is C.A.R.B. exempt on AEM Cold Air induction systems only and is NOT for use on forced induction vehicles. Patent #6,394,128.
AEM's Air Bypass valve for Cold Air Induction Systems virtually eliminates the unlikely chance of water ingestion should the filter element become wet from deep puddles, rain, hail, sleet or snow or any other scenario in which the filter element could encounter or become submerged in water. The valve installs along the upper portion of the inlet pipe on the same axis as the throttle body centerline. Should a drop in pressure occur within the pipe due to filter submersion, the valve shuts down induction at the filter and routes incoming air through its external orifices, eliminating any chance of water ingestion. AEM's Air Bypass Valve is for use on AEM Cold Air Systems only.
