I was looking for one of those old school port tubes we used to use on sub boxes, the square ones that flange down to round tube.. no one sells them.. anyhow.. i was thinking though.. I know on my 97 at least there is about 4" or maybee a little more there besides the Rad/Ac, there is 1 line running through this area that is empty.. I was looking around at something that might work.. and this is what I am thinking..


So.. you would paint black of course... so it would not look so obvious.. but there is enough room here, notice the angle and then the the tube.. there is a plastic bracket there that the AC line secures too.. use this to secure it down.. securing the other side? I'm sure could make a little medal bracket of some sort.. a little paint would tie it all in and not look so noticeable.

(If you look to the left of the Radiator with the hood open there is a small area there besides you could fit a 4-5" pipe or hose, just by cutting the divider there (or removing competely)




So basically if you can image this in your head the first Pic, the part (Painted of course) securing to the bracket with screws, and some other metal bracket and screws, you would arrange the bracket and screw it down the pipe it self moves independent and turns in the bracket.. to get the right angle to go through the area.

From there you could use pipe, or hose.. I would like to find this type of hose longer, maybe a large 4-5" heater hose for big rigs would work.. or find something like this longer:



From there its basically getting a hose/pipe/what ever you like from the mounted #1 pic to the air box..

You could probally use the factory inlet and just cut it back a little to give you a strait in.. or replace it with some other pipe, or something..

Securing a rubber or other type tubing of your choice...

All in all you would get basically just for concept so you can visualize it.. the following:



So all in all you would be grabbing air from outside the hat engine compartment.. and also, this would act, if you really look at that part on #1 pic, it is angled to really grab the air as your driving through it.. forcing air in and into the air box..

I woudl say it would sorta act like a Ram air intake more or less.. then you can follow by a K & N air filter for 59 bucks from Oriely or advanced.. or something..



Thinking about maybee doing it..

It's about 15 inches long and I had to cut a hole in the black shroud behind the grill to get it some clean air. I have a 3.9 with the K&N also and it seems to have given my truck a little extra pep, especially at highway speeds (which "seems" logical due to the ram effect). I made the mistake of several minor mods at once (removed front driveshaft, added the much-debated throttle body spacer - "free" to me - and installed new plugs) and I'm not sure which one may have caused my improvements but this was one I saw no drawbacks to... Next is replacement of the clutch fan with a Taurus fan to try to get some more down-low pep. I also have a Cummins 4bt in my garage that I'm working on too so that's going to be my next major mod to the truck...
Back to the subject though, the burning question I've had, and haven't had the opportunity to test it, is will I have poor results driving in a downpour?
Hope this helps,
PB

Not really.. depending on the setup.. if its just a hose direct up against a filter maybee.. but.. the old fords had an air intake that sat right up top.. it sucked air in directly from between the hood and direct to the air filter..

The only case here is we are exposing the inlet direct... depending on the setup I think you would be ok.. at the least you would need to put in some way of water to escape, but also you would not want a huge hole, because you do not want to much air to bypass the filter either..

I think if you used stock system with upgraded air filter think it would be just fine.. but thats me others oppinions/

Plumbing parts as shown are a definite possibility. I am hoping to find something smooth and flexible that will be easier to work with but I am open to suggestions. Some good ideas coming in, I am worried about getting too much water into the air box also, still thinking about that.

Once I get paid I might start a new thread and give it a wak.. that other thread.. very 'inventive' as well.. seems alot of pipe and excess amounts of distance for the air to travel.. will keep those parts in mind he used though. defint. bonus thread.

Water: I think one of the posters hit the nail on the head, most of the air boxes I have ever seen had some sort of tiny drain hole in the bottom... In this case.. if using a high flow air filter, should not really have the need to push the air excessively.. and should be exceptable to have a small hole or two.. for water to drain and excess air pressure to escape.

Thanks Thunder, something like that is what I am thinking of.

I was thinking about some duct work last night. I used to hang some tin when I did heating and air conditioning, instead of the JB weld he used I think I would screw it or pop rivet it and tape it with aluminum tape. There is also some furnace filter material that is very coarse, I have some it is green plastic. Cut what you need, roll it and stick it in the piping. It would keep the big stuff out, but shouldn't restrict the air flow. The screen wire isn't bad either.

I'm thinking this may be a good spring or summer project.

A large piece of liquitite electrical conduit may also work. It is bendable and has a plastic coating, may keep from rattling. Could possibly do it with one piece with no joints and it is gray in color.

i was going to post the link thunder did. but i got a thread that might be helpfull. i used the stock air box to isolate my homemade cai. and sealed the top with plexi glass. the snorkel is bigger now and i have the top off becase it was sucking rust out of the cavity behind the headlight. i noticed last time i cleaned my filter, but it did work reall good.
