You can get hydro-lock from running a CAI in a wet-environment. The intake will suck up water and run it through the engine, sometimes causing it to seize. You can get a by-pass valve though that prevents this if you are set on a cold air. But there are problems with the short ram too; as in you are sucking in warm air produced by the engine, so you really aren't gaining as much as running a cold air. Now If I were you, I would invest my money into a Volant intake. It's setup like a short ram, but it's also set up kind of like the stock setup, so it uses air coming in through the grill.In theory the CAI should be better. But sometimes during city driving it sucks as much hot air off the pavement as it would under the hood. The rain and snow shouldn't affect it.
