Homemade Jeep Snorkel w/pics

193198 136
OK, I've been trying to use the downtime for the Jeep projects(getting a ton of rain down here). Plus we don't have the nice terrain most of you all do just mud and swamps. So I just got in from making my snorkel. I couldn't justify the almost $400 bucks for the safari snorkle so I welded up 3" exhaust pipe and put on the ARB top.
One 3" U bend $24
One straight pipe $20
ARB snorkle top $ 77
Total $121
All I have left to do is connect it to my stock airbox with some dryer vent tube from Home Depot and some additional waterproofing under the hood.

Tried to keep it low profile for tree branches and wanted it to match the body line and windshield angle. Also I went through the hood because my hood is already dented and didn't want to ruin a good fender.

How's it look?:cheers2:

Mine is similar to Apollo's. Except I used an army surplus ammo can to house the filter. I also used 3" exhaust tubing and welded it together for the stack. The army can works great but it is alittle hard to weld, must be some weird type of metal.

That looks absolutely beautiful! So professional looking.

Quick question: How does it's weight compare to the professional plastic ones? It seems like it would be decently heavy for just the two(?) connection points.

Apollo, What size material did you use and what did you use for couplings?
Check out my thread and see if it answers your question.

2 six to 4" inch PVC connectors

1 rubber 4" to 3" connector for snorkel side (connects snork to intake box)

1 pvc 4" to 2" connector (for manifold side) but if you dremel out the inside you can go from a ~2" to a ~2.75" inside diameter, which is a little better but if I were you I would figure out a way to connect a 4" to 3" connector directly to the throttle body instead of a 4" to 2" like mine, the outside diameter of the 2" part is a little more than 3" and would allow (using slightly larger 3" tubing of some sort).

The hardest part of my design was dealing with the wierd outside diameter of the PVC, the autozone/advance flex tube diesnt fit a larger neckdown than the one on my setup. So connecting the trottle body to my box needs a larger opening and a different type of flexhose that. Havn't found yet.

I think I may have to build one of those boxes soon. I have a cheapy cone filter that is very unprotected. I could do that just to keep the dirt off until I run my snorkel.

I know this thread is a bit older, but my only question is:

Why not just put a cone filter on the top of the snorkel where there are questions as to what top to use? I have a homemade snorkel going into the stock airbox which I have used for several years. Great addition to the jeep, and has been heavily tested under water. It has a cone filter on top covered by a K&N filter wrap (keeps out water and minimizes dirt to the filter itself). This has been a great setup, and I dont see anyone here even consider this.

At the current time, I am searching to replace the stock airbox. I do like the PVC 'shelter' idea, but am looking to remove the box and keep the air filtered from the top. So all I need is something to connect the other tubes to. Got some ideas, and thank you all for that!!!

:highfive:

what happens to the rain if you're driving through weather and it gets in the snorkel?
I've had my snorkel setup for over a year now, and have driven with it in quite a bit of rain (and more lately, snow) and have had no issues at all with water building up in the air box. Had it been an issue, I was planning to put a one way flapper valve in the bottom of the air box (like what's on the bottom of some ATV air boxes), but so far, it hasn't been needed.

the arb snorkel top has cutouts around the bottom that allows the driving rain to be channeled out. If you don't feel comfortable driving with it forward just turn it around backwards, but keep in mine that it will cause a low pressure area behind the snorkel head and can allow small amounts of water vapor to be sucked in. not enough to worry about though.

I think i'm going to attempt replicating yours, i hate the stock intake. it'll be a few weeks cuz i'm in the process of getting a trans and injectors right now. but when i get it started i'll post pics to get opinions on if i'm doing it right or not

an airbox from a 91 chrysler 5th ave works well, It's very small and straight though w/ 3" in and out. The one thing to keep in mind is don't get in a hurry and do like i did and cut your hood too close to the rear of the vehicle. You'll want to make your cut near the front so the hood closes on it correctly. I had to elongate my cutout in order to allow it to shut.
