Your engine needs oxygen to keep the fire burning in its belly. While your AEM Cold Air Intake reaches down below the bumper to draw in the freshest air, it's at risk for sucking in something deadly to performance: water. Equip your aftermarket intake with an Air Bypass Valve for a surefire defense against hydro-lock.

When your intake becomes submerged, your Air Bypass Valve immediately springs into action. It closes off induction from your main filter and reroutes the air flow through its external diaphragm. Plus, the integrated foam filter traps dust and blocks debris from getting into your powerplant.

Built tough to withstand life inside your engine compartment, your Air Bypass Valve boasts a sonically welded, nylon reinforced cage. And, its urethane flapper valves are nearly impervious to the elements and harsh chemicals.

All Air Bypass Valves are 50 state street legal, and most mount easily to the upper inlet pipe. Backed by a 1-year warranty.
