I drove around for several years with a low, almost ground scraping cai in my maxima.  I never once encountered in issues with that.  I drove that car through the worst of rain conditions.  I even splashed up the biggest puddles in the road.  The car never even thought about hydro-locking.  All in all, I don't see how Injen's little bag can prevent water from getting through the filter.  If it's porous, water can permeate.  The only thing that bag is going to stop is that little extra bit of air that I could be getting without it.
