Cold Air intake + Bypass Valve. ?

I'm thinking about getting a Cold air intake along with a Bypass Valve to prevent Water Indigestion on my Toyota Corolla 07. I was wondering if Bypass Valves actually work and can someone explain to me the physics around it???( How bypass valves work)

Update:

where does the Bypass valve go on the cold air intake? does it go next to the Filter? or next to the cuppler (connecting the tube to the engine)?

Update 2:

sorry i found out. Can i mix An AEM Bypass Valve with a Injen cold air intake???

    The AEM Bypass Valve protects the engine from ingesting water and hydro-locking if the filter becomes submerged in water. Hydro locking occurs when the end of the inlet pipe is submerged in water and the water is sucked into the engine. Driving the vehicle in rainy conditions is not enough to cause a problem unless the vehicle submerges enough that the inlet end of the pipe is immersed in water. Rain impingement on the filter will not cause a hydro lock condition.

    The distance of the filter from the road dictates the level of water that can cause damage. This distance varies with the vehicle ride height, which is why there are no published numbers for this measurement. We suggest taking this measurement and keeping it in a log book, so that in the event you encounter deep water you will know what your maximum allowable depth is before potential submersion of the inlet pipe.

    All AEM Cold Air Intake installations retain the factory splash shield (fender liner) for filter protection and performance. Removal of splash shield actually deteriorates performance by allowing air heated by the pavement to enter the filter and negates any positive pressure created in the air filter area when the vehicle is in motion.

    There are some instances where there is not enough room around the inlet pipe for adequate clearance of an Air Bypass Valve. In these instances, we recommend installing a Short Ram system if water ingestion is a concern.

    Get a straw and put it in a glass of water. Suck the water up the straw and what happens? Get that same straw and punch 6 holes in the center around the straw. Suck on the straw and what happens? That is the purpose of the bypass.

    Now the speculation behind the bypass is the intake system has to be fully submerged for it to work efficiently. Get your aftermarket straw and hold it sideways nearly touching the top of the water and suck real hard. You will notice water gets to your mouth, and so your engine. Nothing more than a pressure differential.

    Bypass valves are very expensive parts for people that don't understand principles of pressure and vacuum. Don't waste your money on it, but stay out of deep puddles.
