i was thinking about getting a ram air or cowl hood, but i can't stop thinking about what if your cruisin and it starts to rain? if you suck water in there, i can't imagine it would be good. What are ways to prevent this if there are any?

 

How many thousands of F-Body, or any other type of cars, come stock with Ram Air? I think the design of the hood takes care of that for you. Dont worry about it, just get the hood you want and then show us pics.

 

There should be a way for the water to get out before it gets to the filter, baffles and drain holes.
Then the filter should catch what's left.
