AEM patented air bypass valve virtually eliminates the chance of hydro-lock in the unlikely event the filter of your AEM Cold Air induction system becomes submerged in water. 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 for use only on AEM Cold Air induction systems, and is not for use on forced induction vehicles. Pending C.A.R.B. exemption. Actual product may vary slightly from image.

Universal fitment for most 3-Inch diameter intake systems.
