Went out today for a fathers day ride with my dad and his kubota RTV. My buddy also went in his hi-powered brute force. Tested in some moderately deep water, mine isn't lifted for reference. after 6 passes back an forth through the water crossing i had about a 1/4 cup of water in the air box. I will be siliconing all the rubber fittings in the airbox, but i think it did fairly well. i am extremely happy with it so far.
