What if you hit the water to hard or some how it splashes up the like say it runs off your wind shield? Wouldn't that get your air filter wet if you had a cone one or have the water run into the box if you have it going into the box stock air box?

Thanks I'm new to this but it just seams like the water would run off your wind shiled and into your tube?

 

If guns don't kill people, people kill people. Do toasters not toast toast, toast toasts toast?

The cowl isn't a very porous thing, a lot of the water that gets on it or near it runs off. If any gets in it, there are drain holes. Also, unless your filter is in contact with the bottom of your cowl it should have a difficult time sucking water. Another thing, if you run it to your stock airbox box box thingy shaped like a box, the water most likely will just fall to the bottom.

I'm just giving you crap man don't take any offense

 

The cowl has large drains - one on either side of the truck. The tube to the airbox also sits ~3/4" above the bottom of the cowl, so it's nearly impossible for water to "run in" to the airbox. The beauty of using the stock airbox is also that the filter is in the top, so even if you manage to get some water in the box, the engine won't suck up water.

This is the biggest splash i've made - went over the windshield and cowl like you described. I ended up with only a few drops of water in the bottom of airbox from this dunk.

 

LOL okay thanks I wasn't sure glad to hear tho I deffently want to do somthing like this I had been thinking a snorkle but I like this idea here


Also I haven't heard anyone really talk about it before so, what about doing somthing like this but moving the tube all the way inside of your jeep? So that your intake is inside somwhere? thoughts on that? Just somthing diffrent I thought of while thinking of spots to move the intake too

 

You could run it up the a pillar on the inside of the jeep and have it sit at the higest point of the roof if you really wanted, but i think that might be a little overkill.....

 

Here is a video: Mine is the silver XJ. Enjoy.

 

Im surprised to read this whole thread and not hear some more comments on this dudes settup. This is absolutely sick and exactally the "humvee" type intake i was envisioning wanting while reading this. So sick.

 

I like that mine is hidden

 

Hidden is nice

 

I'm all for this design. We often wake up to a lot of snow here in the winter and I see this a better deal than the filter in the cowl and totally covered. Is there a link to what he used to build this? I want to do it to my 89' 4.0 and my buddy needs the same for his 88' with a newly installed Mercedes 4 cylinder smoker.

Nice jeep but two things.

I don't like how the filter is "in line" This can lead to filter damage.

I don't like that the water has no "trap" like in a stock air box. So the water can go directly into the intake.


But it looks good.

 

About the snow concern: I had 4+ inches of wet heavy snow on my cowl and had NO ill effect to the engine breathing, I run with the "torque" app on my phone connected to the OBD2 reading almost everything the computer puts out and there is nothing different in and vacuum numbers or what not. Revving the engine was as smooth as a sunny day.

About the "trap" concern: Water would have to go up into the exposed tube BUT Check with me here I think the Spectra setup pulls air from the cab not the cowl?? (without the added exposed tube)

Even if from the cowl there has been many comments about how well the cowl either drains any water in it or it isn't porous enough to allow gallons of water to enter.

Honestly I have read so many grips on this setup, it really needs to stop! Bottom line: this setup "WORKS"!! end of questioning! And all for 15 bucks if you already have a 3" hole saw or access to one.
Get off it!

 

This is my version. Filter in the cowl and in HEAVY rain i have no trouble. It sounds so good at WOT so thats a plus.

 

Great thread... this mod is definitely on my to-do list now!

 

I want this setup, but with the stock air box and filter.
