Homemade Jeep Snorkel w/pics

193256 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:

If rain which runs down the snorkle drains through the airbox below the intake... What's the point of the snorkle? If water can drain out the air box can't it get IN as well in deep water?
I'm not sure what everyone else is doing about this, but here's what I'm going to do.
have you ever seen the bottom side of an ATV air box? they have a little one way valve(some are a diaphram/flapper type, others resemble the cowl vent drain tube on YJ's), that will allow water to drain out, but will not let it come in. I'm still looking for one, but I plan to put one in the bottom of my air box to let rain water drain out.

I think your 441.4 CFM figure is a little much.
acording to the cfm formula found here,
Classic Inlines CFM Calcs and Volumetric Efficiency
the 2.5L engine only draws in about 221.9 cfm @ 5000rpm.

you have to remember that because these are 4 stroke engines, they require 2 revolutions to draw in their full displacement volume.
i totally agree with muddy. i used to be a chevy hot rod buff and for a 5.0 305 sbc stock with a quadrajunk carb they were only pulling around 500 cfm.

sense this thread got brought back to the top, I'll add a little update to my snorkel.
I got it painted(along with the rest of the jeep), and found a pic of the adapter flange that I made to conect the snorkel to the stock air box.
Painted, sorry, it's the best pic I could find.


and here's the adapter attached to the air box. I also put in a bung so that I could relocate the intake air temp sensor.

I'll revive for the above post. I would like to use this on my LJ. It looks very clean and professional at a fraction of the cost. I like it better than the actual producers of snorkels designs such as ARB.

I made a new airbox all together to get rid of the whole "box" design which has many 90* angles and well, it's a box... air goes into the box and goes many different directions as it hits the corners... I just picked up a 40.00 K&N 4" filter and built a PVC housing. Some say the sizedown at the end is too much, but I saw a performance gain when I installed it, and when I pull the hose off the throttle body, it makes no difference in the engine idle, so despite what some have said, PLENTY of air gets through, enough to add 1MPG to the list and a higher top speed.

Anyway, dont know if this helps, but I built the airbox (minus filter) for 40 or less.

How are you recharging that air filter? Will you have to destroy your PVC air box to do it? Or are you not cementing it together?
One of the 6" to 4" pieces isn't cemented on, I used buckle clips from lowes and epoxied them on the sides so when I use those clasps to clamp it shut it seals around the rubber rim of the filter. I usually silicone/rvt around the one spot that isn't cemented "just in case" but I tested it using some cynder blocks and holding the thing 6' deep in my pool and no water got to the filter lol. (I sealed up both ends to test it but yeah water didn't make it in through the cemented parts nor the buckle/clamp half).

just ordered my pipe and am ordering my top tomorrow. I'll post up photo's when I do this to my LJ on the passenger side.
