Hydro-lock on the tC is only going to occur if you drive thru 2ft+ deep puddles. Look at where the air filter is and you can see that it is encapsulated by the front fascia, radiator air diverter, fender, and mud guard. Plowing thru a puddle is not going to ingest water. Plowing into a 2ft+ deep trough of water will. There is always a water sock which is cheaper and easier alternative to the bypass valve.
FYI. The AEM bypass valve is not really a valve. It is just a plastic ring with holes around the circumference covered in a porous foam filter. It uses the "path of least resistence" principle.
