your airbox is under the seat, i'm not excactly sure but long as ur not abov the seat ur fine, also like blaster freak says do not let off the gas becuz your preassure on the pipe will help try to keep water out of the pipes, my friend was an total idiot he was going threw a mud pit and he decided to switch gears put as soon as he let off mud and water went into his pipe causing him to stall out, we had to clean the whole engine out, its running like sh*t becuz he sucks at mud bogging so bad one time he got stuck agian, stalled out, pulled it out rode it back and kept on riding it day after day, and he had to replace some gears and other expensive things. i hav eno problem going threw deep mud pits, i only get stuck a little soemtimes but i always get out.
