i did the same thing as OSX works great. for an added sence of security i drilled a couple of holes in the low spot in the airbox in case any water does make it up there, it will be able to drip out. ive drove in some hellacious rain through some deep ass puddles and water has never been a problem. also you can block that tube in the intake pipe cut the peice you dont need out and vent your valve cover if you want too.
