I just did zoodad mod on my truck. Can there be any problem with water in the air intake system, from driving in rain or washing ?

 

yeah, if you are driving in a hurricane or if you intentionally spray alot of water down the snorkel. If it bothers you, put some duct tape over the hole durring the winter or rainy weather. A friend of mine came up with a good idea with a hinge and a piece of rubber or plastic to cover the hole.
