that sucks man. hopefully you got it all out or your engine will blow up like forcefed's did. I think there was something about the AEM
that the bend in the bottom holds water instead of draining out because one of the bends is lower than the pipping so you have a place to store any splashed on water. from the sounds of the storm though sounds like you may have actually submerged it. haven't gotten any really bad storms yet here, did have a few inches when I first got my CAI
and I drove around all day without a problem though.
