I have a uni foam on a K N air tube and was in some fairly heavy rain. Looked at it when I got home and the sock had sighns of water but did not notice any difference in the way truck ran and no steam out the exaust. Rain lasted maybe 10 miles an I was running 60 to 70 in it. hope this helps.
Let me ask a question. Wouldn't a foam filter act like a sponge and pick up moister from the air and retain it? If so; wouldn't it become a partial air restrictor? I keep hearing all kinds of storys about foam and since i have had no experience with them i don't know. thanks
I have the aFE and was surprised at how much sh*te gets onto the filter and box through the headlight / grille.
If I would have known, I would have bought a sock and/or put something in the open front of the aFE box to prevent this from happening. I'm not having a cow about it, but it just doesn't look good at all.
I think it came from following trucks on the interstate in really sloppy conditions, but there's not much that can be done about that.
hehehe maybe I should jam a big UNI filter in the front of the airbox.
