Product Description

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 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.

  • Virtually eliminates chance of intake system ingesting water if filter becomes submerged
  • Installs along upper portion of AEM intake systems with minor modifications
  • Patent #6,394,128
  • Complete hardware and installation instructions included
