NOT GOOD.. It looks like someone added that hose.
The original intake went straight down and had a flap over it to prevent water from getting into the air intake. It didn't work. Ford issued a TSB and replaced the intake with a "J" shaped tube that had a couple holes drilled in the low point to allow water to drain out.
The "J" tube isn't available. I used a flexible irrigation tube that has holes in it to allow water to drain.. This is what I did:
