86-92 Toyota Supra 2.50" Air Bypass Valve for Cold Air Intakes Red
The Air Bypass Valve virtually eliminates the chance of hydro-lock in the event the filter of your 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.
