No, basic physics says air will take the path of least resistance. If the cone filter goes completely submerged in water, the air will pass though the stock intake snorkel and not the cone filter. You will have no issues with hydrolock with this setup. Now if you have a pure CAI, with no stock intake snorkel, then it will hydrolock if you drive in deep water. You can also adjust the height of the cone filter as needed. I live in a very dry climate so I have a completely exposed filter, if it rains where you live, feel free to tuck the filter up behind the bumper.
