Well one of the guys here recently toasted his engine by driving through puddles fast with the a K&N FIPK but he also had no inner fender liners. The K&N offers no shielding of any kind around the filter. I sold mine because of this. I would only get a Volant intake since it places the filter in a box. Also you can buy an outerware to help keep water out. Just don't go into anything really deep. I have had water get in my stock intake while driving too fast through puddles.
