$20 XJ snorkel. Pics of what I did.

[HaZakated]

Click these links to veiw exactly how i built my snorkel....
I welded the bracket directly onto my Jeep.
I used a sealing adhesive to seal the PVC to the air box.
the PVC goes into the air box about an inch.
I used a 2 1/4" hole saw to drill the hole in the fender and airbox.
U might want to use a 2 3/8" hole saw because the 2 1/4" was a bit to small.
I used standard PVC cement to seal the PVC together.
I painted it gloss black and added my decal.
you can be creative when sealing up the stock hole on the air box.
I simply use duct tape, and remove it when driving one the road.
This mod also gives you some added horse power when both holes are sucking in air, while driving on the road.

Nice Job! Thanks for the pics.

[Kittrell]

Looks nice, how did you go about sealing the airbox????

[HaZakated]

I used a sealing adhesive called WELDER, and rubbed it around edge of the pvc pipe and the airbox on the interior and exterior of the airbox where the pvc enters the airbox. When I go off road I put duct tape over the stock air hole, and small holes at the bottom of the air box. Duct tape is water resistant if used correctly. Just put 3 or 4 layers of it over the hole and remove after your done 4wheeling. I go wheeling about once a month, but if you go wheeling alot you can use a rubber stopper to seal the hole. You can just mend a piece of plastic over the stock hole from the inside of the airbox and seal it with a glue and some silicone. If you have a saudering gun, use that to melt the plasic together for a welded seal.

Thanks man i do have to say im doing the same thing very very soon.....Great idea! Thanks again.

[HaZakated]

make sure you drill the hole in the fender in the same area I did...that's the only real thing to be very carful of. If you run into any problems, my e-mail is

I like the wheel and tire combo. Looks Good.

[coderedxj]

Is there any way you could have made a better cut in the outside of the fender? It looks pretty rough. Other than that, it looks like you did a great job for the money you spent.

[Ludakris]

I see one rather big problem. You cant remove the air box. if you need to do anything on that side of the engine, or deal with brake lines, p/s etc, your air box is glued in now. also.. I dont get the duct tape.. why not just permanantly seal the front up? here is what I did...

With the rubber piece (also found on the plumbing section) I can remove the box after removing a hose clamp. I also sealed up the front of the box with a piece of sheetmetal and silicone. I used steel pipe mounts, bent and screwed into the A pillare were the door closes. very simple, very effective.

[HaZakated]

When I need to remove the air box I will simply pull out the pvc pipe and put some more sealing adhesive around the pvc pipe when I put the air box back on.
Brian

[HaZakated]

Good point though....with a rubber peice it would make the job a little easier if you ever had to take the air box out. But I wouldn't consider it a rather big problem.
Do you ever hit the snorkel with your tire. I know my tires go very far up into my fender well when at full articulation.

Brian

[redyouch]

there is nothing better than trying to sell a newer xj with a gaping hole in the fender and square box welded to the A pillar

do you think that it sticks out too far and might get ripped off by trees

[HaZakated]

as far as the cut in the fender....acually, the part that looks rough is the weather striping that I tried to put around the cut. I would advise anyone trying to build this snorkel to use black weather striping, not chrome. There is alot of dirt and mud around it too in this pic. Some times I have to touch the snorkel bracket....no big deal though.
Brian

[HaZakated]

I wont sell it....But if I had too, I think that its a little late to target an older generation.
Its extremely solid though; trees wont hurt it as long as I dont hit the trunk or something. I play it smart off road. I want a vehical that is road worthy and somewhat trail worthy. But if I did smash it...I have tools...I'll fix it. It dosn't sit any further out than the mirror does; it sits in further acually. If I had alot of cash, I would buy an old beat up XJ and tranfer all the mods and seal and bondo the hole on my 2000. Most things that can be done, can be undone with the right tools.

Brian

[Zoro]

Hey I like that snorkel, where is your washer fluid resevoir?

[HaZakated]

The resevoir is in front of the cut, about a foot closer to the front of the Jeep than the hole.
thanx

havent had any problems, but I also have extended bumpstops. But with 3" or so of lift and 34's.. no problem. The snorkel is tucked in the fender very well. also i didnt have to move anything.. just drill two holes...

[HaZakated]

how did you get 34's on a 3" lift....Can I somehow? I only have 31-10.50 tires and I had to trim some of the plastic shell out to get them to work. Mine articulates nicely but I would definatly be interested in 34's whenever I look into new tries.
Brian

[Ludakris]

check out my homepage... just get a 4 1/2 in grinder.. and start cutting.. take that plastic inner liner and ditch it.. if you need flares.. go TJ or YJ..
check out CheapXJ on the boards.. had 36's on 3" of lift.. I am going to get some front springs to give me 4-4.5" of lift and I could theoretically fit 36's or so.. but I am afraid the axles wouldnt hold up.. so the 34's will stay..

[HaZakated]

do you run a sway bar in the rear? do you have all your bump stops extended?
does your rims stick out further than stock rims do (is the offset different)? do you think that this would be a factor in me putting 33's or 34's on my jeep?
in other words, if I were to trim my fenders and put 34" tires on it, what else would I have to do? I have my TC lowered.

[jeep1947]

On a 4 dr it will be hard to fit 34" with 3" lift bc of the rear door. You will need to go flairless or use tj flairs and do alot of sheetmetal cutting, and also extended bumpstops. It is possible, but it will be alot of cutting and work.

Anything can fit with imagination and a sawzall :)

[Gil BullyKatz]

Big thumbs up for tearing into a nicely undented, non rusted XJ...

Kudos for not caring about how it looks...

Be proud of your work...

You didn't pay a coupla hundred bucks for "fancy" abs or pvc...

Now go fording and videotape it.

[HaZakated]

I like your style of writing Gil.....
thanks

Brian

[small pederson]

haha resale value, sounds like my dad :laugh3:

[Gojeep]

It is a pity that you ran so small a pipe. You must at least run the throttle body bore of 60 mm and that wont even compensate for all the extra restriction caused by the added length. You dp not even have any ram air effect to help it along either. When doing flow calculations for the XJ snorkel by Airflow engineering, 3" was needed to deliever enough flow at WOT.

Hey Hazakated, is that a BBQ grill you're using for a front skid?

I dont buy that. The OEM opening is 2" by 3" and behind the headlight. not much flow there. The added length is something.. but I dont see major HP losses. The aftermarket snorkels I see go from round to square to 90 degree bends to flexible hose. I would bet my 2" constant ID PVC has more flow than a Safari Snorkel... the length as well as the Air box, take any Ram Air effect and throw it out the window. Besides, if I wanted HP I would put an open air filter and Scoop on the hood.. I just want my engine to survive a water crossing...


The flares were $30.. and do the job.. and the front ones have a nice beer holder in them..

[HaZakated]

Ive never had a problem with air flow Gojeep....When Im not off road I open the stock hole. Off road the snorkel does great. It seems as if I get the same horse power if not more really. Engineers say alot of things to get you to buy their products. I would know, Im studying to be one at Miami University. Here's a copy of my mid-term grades I just recieved.

lol.....bbq grill.....its a rack that goes in between the racks to hold up the skids at an old job I worked...BBQ grill..lol...I once incorperated a socket wrench into a design of mine though. Hey, if it works, use it.
Brian

[XJRubicon]

craftsman sockets make the perfect spacer on a dodge alternator...

[Gojeep]

I dont buy that. The OEM opening is 2" by 3" and behind the headlight. not much flow there. ..

A 2" pipe is way smaller in area than a 2"x3" hole!
You are looking at 2124 mm2 verses 3952 mm2!! You are just in that nearly running half of what many say is too small an opening to the stock box!
Dont discount ram air as many on LPG have had to turn their snorkel heads sideways as the gas meterage couldn't cope with the extra pressure on some models.
Why dont you just work out your CFM for a 4.0 litre at 5000 revs and compare that to the flow rate possible for a 2" pipe?

Just trying to point out a short coming to help you and before others follow your lead. If the snorkel is only used when crossing water where you do not ever see high revs it is an adequate idea and no different to the one I ran myself until last week to the top of the firewall. Was just worried for those that do not do this and has it breathing through there all the time ;)

thats a 2x3 inch hole that is shoved behind alot of stuff... besides that it goes into the air box... Am I starving the engine at 5000rpm.. no I do not believe I am.. the ram air is still not an issue.. turning sideways would cause more of a vacuum than turning it backwards.. but back to 5000RPM.. christ, that is almost at its redline.. its not like I am drag racing this thing.. Its used offroad... I would be surprised if I hit 4000 rpm.. When my engine starts starving for air.. I will let you know and go over board with a 3" pipe.. cause we all know that bigger is better, that is why engine builders dont bother tunning intake runners, they just make them as big as possible..

Nice report card Brian, but I don't see your grade for course NEWB ENG EGO 101? Guessing your doing well in this one though.
What GoJeep is trying to point out is that your pipe size sucks....and not in a good way, tuned runner? Hehehehe Learn to accept constructive criticism from folks with hands-on knowledge, it'll make you a better engineer.

I'm not an engineer either, but I do know one that cooks a mean tri-tip......

Yep it is Good to listen. Wasn't that how those A+'s got on your report card.
Good job by the way.

[HaZakated]

Your right....I shouldn't have put my mid-term grades. I understand what he was doing. I was trying to establish some credibility with my grades. I said it like I knew it all......... 3" pipe would not fit into the setup I have. I agree that if you cover the stock air intake hole all the time, it only makes sence to get bigger pipe to compensate for the added air travel distance. I didnt do the math though.

sometimes, even the older wiser people with hands on knowlege get to sure of themselves. kinda like this message I recieved from you...

(Nice report card Brian, but I don't see your grade for course NEWB ENG EGO 101? Guessing your doing well in this one though. What GoJeep is trying to point out is that your pipe size sucks....and not in a good way, tuned runner?)

I worked hard and long for those grades and yes I am proud of them. I am 25 with two little jeepers of my own. I have been slaving in construction and forklift operation for 6 years, and now that I have this opportunity, yes I am proud of them. Your right though, I came about it the wrong way. No excuse. If your relating my pride to my ego, then yes, I have a huge ego.

Brian

[Richdaman]

I have two 4 year degrees... but who really cares? I think you both have valid points, but I am going to lean towards having a little larger diameter, especially with the distance involved. A good source of air is critical so you don't want to error on the short side. Nice engineering though. Way to take the initiative! And yes, it is good to listen... there is always someone that has tried it before you...
For anyone reading that hasn't replaced their stock air intake, you might want to take a look at how limited it really is! I couldn't believe how choked my engine was until I tore out the OEM garbage!

Good job on the low buck snorkel and the schooling Brian and your ability to take a jab.....not gonna repeat the PM, we're square.

[BigDawgz]

Your low buck snorkel looks good. I was just wondering why it wasn't turned around like the Safari Snorkel's? I figured it might of been because of the rain.?.maybe... I know that the Safari Snorkel addresses the rain issue within it's design somehow...at least from what I've read about it. I think it's cool to do low-budget mods and save hundreds of dollars. GOOD JOB.

Yeah you keep hearing from the Adminstration about supporting the troops. When are those idiots gonna step to the plate and do the same for the troops and the veteran. About the same time they quit worry about making Corporate America richer. Just don't hold your breath, and thanks for being there for us.
At least you guys are worried about the good ole USA.
