I ride in a lot of water and mud sometime, i live close to the Atlantic ocean. I found that removing that clear plastic cap under the airbox help. It let more dust to go in, Outerwear take care of it, but it drain the water quickly and prevent it of splashing all around the airbox and on the filter. But like the others said, avoiding water holes is the best, because when you fil your boots with water nothing else is gonna stay dry :sweat:
