Its the fact the air and water are moving fast, rain will fall side ways and even upwards of the wind is blowing hard enough and in the right terrain. And the 3 way definitely doesnt solve the dirty filter issue.

Joe, my thoughts exactly! But, here in Tucson, we have many dips in the road that fill with water if it rains (admittedly rarely). The "low down" intake without a vacuum break (provided by the "Y" in the reference Longshot posted) would guarantee water into the cylinders.

Now, with the vacuum break, the water would probably not be sucked up at city speeds. But, you hit a big puddle at highway speeds (or the vehicle in front does) and you have big water drops at high velocity going into that intake. I'm not confident that they won't find their way into the engine. Personally, I think a "ram" intake needs to be on top of the hood.

Even then, I'd want some kind of water separator. It's possible, as you probably know, to "drown" a jet engine in a heavy rainstorm. A recip would just be destroyed.
