I still always have a hard time believe this. My filter sit’s a few inches from my tire and there is NO wheel well. I’ve driven hours and hours through HARD rain (Arizona monsoons) in sometimes water up to the bottom of my car at a stand still. Whenever I get home after this I check my filter and it’s always dripping with water. Still haven’t had any issues. I’d still take this warning seriously though, just thinking about how many factory cars I’ve seen still get flooded out in our monsoons.
