I am interested in one for its real application, dust. When traveling in convoy as most of us do pretty often dust can kill. In Australia they sometimes even use oil filled prefilters like the ones on some tractors. If you are into stuff that goes up to where your intake is you have more problems than just electrical, if you hit the water fast fan blades beat on the radiator, and a gnasty thing known as "hydro-lock" could happen which I could never put my precious VX through. How do I know this? I've done it, it sucks! (with an old fuel injected ranger) Water is our enemy (sometimes) snorkels help keep our filters clean, and some integrate breather hoses for other components as well like on naturally aspirated rigs. If its deep enough water can also get into the gas tank or sand and water can enter the axle via the axle vent tubes, or the engine via dipstick hole. Electronic things aside water is a fickle animal, alluring yet dangerous. In conclusion stay out of lakes and stick to the trails
