chances of water being drafted into a cold air intake depends on a couple of factors. first, how low does the pipe go. some CAIs pipe does NOT extend to the wheel area of the body, it is much higher up than that. there are some CAI pipes that just go below the battery engine firewall but not low enough for water to be drafted UNLESS there is a severe flood. the second factor for water being drafted by a CAI also depends on how low your car sits. a car dropped 2 inches obviously has a greater risk than a car not dropped.
SRI has the myth about not drafting enough power or being weak and pointless. some of these are true and some are not. once again, the main factor depends on the pipe length and bends. if the pipe bends are long enough and far away enough from the actual crankcase area, where heat is generally dissipated, then you will not draft enough warm air to hinder performance. if you go with cheap eBay brands that are just a short pipe that lands the fitler directly next to the crankcase, you are drafting in a lot more warm air. so, sometimes, buying brand name that's been through R&D pays because they design the pipe to hide next to the battery where it is the least warmest possible.
either way, you are drafting more air with any type of intake. so both will yield positive gains, unless you use some weird one that sits in front of your exhaust manifold.
