"Waterproof Your Cold Air Intake System"

AEM's patented Air Bypass Valve eliminates the chance of hydro-lock should the filter of your AEM Cold Air Intake System become submerged in water. The Air Bypass Valve is only for use with the AEM Cold Air Intake System. In most cases, the valve installs along the upper portion of the inlet pipe and shuts down induction at the filter when submerged. Air is then rerouted through its external diaphragm to keep water out and air flowing in.

Key Features:

• Durable, sonically welded, nylon-reinforced cage
• Urethane flapper valves
• C.A.R.B exempt (50 state legal)

NOTE: The Air Bypass Valve is not for use on forced induction vehicles.
