Maybe this is where the issue is. Mine is sealed where the air box enters the cowl. Yours, being unsealed, might be drawing enough air from the engine compartment to cause a whistle. Just a thought...

hmm paper towels stuffed around it would prove or disprove this theory. Sweet, I have something to work on tomorrow. How did you seal yours?

I do think that gap is the cause of your whistle. It could also be the the raw end of the box itself.

Mine is sealed using the Windstar horn from the fender. See my posts further up in this thread. I also went to the auto parts store to find their fattest piece of radiator hose to extend the horn a little into the engine bay to line things up and make everything good and tight. Something from a big truck. I'll take pictures of the radiator hose soon...

I think you are right. Maybe the swirl effect from the flared opening is causing it. That radiator hose idea might do the trick and help avoid water ingestion.

For anyone still debating on what to use to combine the cut piece, I used plastic weld from advance auto. Its been at least 3 years and i've never had an issue with it.

Here is the horn and radiator hose entering the cowl behind the air box...


... and the horn/hose/air box assembly.

I added the hose because the mess of Jeep wires kept the air box from fully seating and sealing against the horn. All three pieces are effectively one unit.

The piece of radiator hose is flared and acts as a sort of reducer coupler/street fitting. I don't know what it belonged to. I just walked into the store with the intake parts and found what worked. The hose was cut and assembled in the parking lot.

FWIW, notice that I carved off all the Ford bracketry from the air box. I felt this allowed the air box to sit better in the new engine compartment without the unnecessary bits getting in the way.

This is the horn sticking through into the cowl.


Because there are very few clear images of the holes we drilled into the cowl, here is mine.

Today I discovered a very unfortunate unintended consequence of cowl induction and a true cold air intake.

I have had my Jeep since late-spring of this year. Several times over the summer before a long drive I have wrapped my lunch up in aluminum foil and wedged it between the intake and exhaust manifold. Several hours later, I would have a hot meal ready. This morning I did the same as I have done before. A few hours later I stop for a snack only to discover my bratwursts are still cold! I also noticed that the intake manifold was quite cool to the touch. Nearly as cool as the body of the Jeep. Only a small corner of my aluminum foil packet that made good contact with the exhaust was warm. I have every reason to believe a K&N cold air intake would have provided me a hot lunch today.

I consider this further evidence that the Windstar intake does, in fact, provide cold air to the engine. Please plan your day accordingly.

I finally got around to getting one of these horn pieces off an F150 and it did help. There is still a little whistle when I accelerate but so far thats it. I will know for sure when I make the trip to Corpus next week. Really gets loud on the highway.

I finally completed this mod a few weeks ago, 98 windstar box with extra rubber boot that goes through the cab. Upon startup i hear it louder, sometimes when accelerating a little i get the slight whine. My problem is when i floor it I get lots of noise but seems it wont really go anywhere. The tack goes up but jeep wont seem to accelerate faster. I usually just back down on the gas but today i kept it on to see what would happen. I got a code p121 which says TPS which i cleaned a few months ago. Has anyone else had this problem?

Try replacing the tps. Try it without air filter? Air Restriction ?

Everything up to this point I will argue is normal for the Windstar intake. At least this matches how mine behaves. The rest, i can't help with.

Still got it. Might not be as loud but it is still there. I hate it lol. There is a little pin hole on the bottom that I believe is for water drainage. That might be causing it. Not sure. I did notice that the cone I have is not the same one however. Got mine out of an F150.
It did allow me to run my wiring over the air box putting it back in the stock location so that is a plus.

The drain hole on the back of the canister? Mine is still open for drainage. I am inclined to blame the F150 cone. Very odd.
