dirt cheap intake. bought a used (on the highway) k&n, 3.5" inlet.

3.5"od abs sewer pipe. this was a really tight fit into the factory 90deg elbow to the tb. had to throw it in the tub in hot water to soften it up enough to get the abs in there. no wife, no problem! the dog didn't mind.
I used a copper fitting and drilled into abs for the breather, them blobed it together with epoxy.

the clamp is scavenged from the air conditioning. it held on some stupid thing in the way, by the distributor. perfect fit, it unbolts, too. goes down to the old airbox stud.

and the heat/splash sheild is thin sheetmetal, screwed together, with a floor too.

watch out if your an xj guy looking at this, the 3.5"od abs is too big to fit your 90 bend at the tb. get a used zj one, or get a zj, bitch.

i have been plannign to do this for some time now. but as soon as i do that i will want a snorkle. then i will have to tear it apart. goot tech tho. i'v got a few PVC pipe snokle ideas up my sleeve i will save for a rainy day. But definatly looks good.

I did a similar thing, but used 3" exhaust pipe slipped into the factory rubber tube (V8). I went to a muffler place and asked for two feet of pipe and they gave it to me. Total cost $50 for the K&N...

Chop: What did you use to cover the AL shroud? Door edge moulding?

What part # for the K&N? I may have to do this when I install my tc to p-pump conversion. The P-pump may (just a little) want to push into the stock air box.

id like to see something different with a ""snorkel"" going up towards the plastic between the dash and firewall the black part that sticks up out of the hood. a FIPK is just too susecptable to water/mud intake and hydrolock is bad, my stock airbox is covered in mud/dirt/water evertime i wheel i don tthink this is a very practical application for wheeling. for street yes very! but not for offroading. :oops:

the edging is vacuum line off some 70's rig I had laying around. sliced down the middle, exopied on.

having the intake snorkle'd up by the firewall would def. be better, but I don't think I'm any worse off in this location with the open element compared to stock airbox. the shield takes care of that. the bottom of the filter is higher than the stock airbox inlet, so if I'm straight up floating in a bog, I have an extra inch or two there. And the shield is tight enough to block splashy waves that make it to headlight level, if it's just one or two. I left a corner at the back of it open to act like a drain.

I had a filter given to me for free. It had a 3" ID intlet so I got a piece of 3" exaust pipe, had the shop widen it 1/8" for me, then found a PVC coupler that fit the 3 1/8" tube and necked down to the 3" ID filter.

Then I welded a little mount to the exaust tube and called it good. Total cost, 5 dollars.

No noticable performance gains, but I do have a blingin chrome filter.

just an autozone special ghetto filter. I was in a creek not long ago up to my headlights, and some points over the hood and it worked great. The only thing that caused me probs was the coil being underwater.....which shut it off. Pretty easy mod, fits really well.

As an alternative to K&N filter, S&B makes high quality "pop-charger" style filters that include an inverted cone on the front to increase the surface area. I'm running a 7" filter w/ 3.5" id flange, which they claim will flow 1272 cfm, way more than I need.

You can also gain more airflow by cutting the stock air hat in half and fabbing up a 3/4" spacer to create a poor-man's FIPK.

I modified my airhat a long time ago the way you mentioned above. Actually got the idea off JU ages ago - long before their newbee downfall. Right now, I have it hooked back up thru the stock air system, with a K&N Flat panel filter I bought when I got my Jeep new. Since a big part of the restriction in the stock system was the airhat, I still receive some benefit from this setup - but not the kind of benefit a FIPK II setup would give.


Before modifying my stock airhat, I actually ran an Edelbrock ProFlo modified air cleaner on the throttle body for a year or more. It was extremely easy to modify for fitment, flows air (albeit hot engine compartment air) like crazy, and was loud as hell. At the time, you could get ProFlos at Autozone for something like $17. They may still sell them.

Thanks for the pics, Chophouse... I got most of what I need to move to that setup eventually. For some reason, I'm liking my modified stock setup for now.

i made my own intake. I got for free, a True Flow intake tube from a frined's '01 Eclipse. Their's was teh proto type, and got it for free or sumthin, so they had no use for it when they traded it in. I cut off teh 2 ends, and clamped it onto teh stock intake tube, then bought a cheap auto zone air cleaner, and used some thick banding to support teh whole intake. Viola, no more air box.

Here are some more pics for future searchers (gasp).

Enlarged stock airhat running into abs pipe and then into a 7" S&B powerstack. The sticker is good for at least 5hp.

thats just asking to suck water IMO. I guess you'd just have to watch water crossings. Probably sounds good though!

sticker? who cares?

Ya, water......it's no snorkel, but it is 4" taller than stock intake, with a splash/heat shield. I like the pics of the one turned up towards the firewall. I prefer under the hood on my dd.

This one is on a commuter, dude just wanted some milage increase, it's the first thing he let me do to his rig. Certainly not super hardcore or anything, just thought I'd throw the pics in there.

Next one, I'm going to use exaust tube instead of ABS.

i got the sticker with my filter when i made mine. :roll:

Making it for the 4.0 is beyond easy. The airtube is not as restrictive as the 5.2 so its not a problem. I got a piece of 5" pipe or so from Lowes attached my massive 10" filter to it and made a little bracket that bolts through the existing airbox holes. Dont have a heat shield yet but I doubt its suffering much from the extra 30 degrees.

I have the same setup that Alaska ZJ has. I tried 3" but no way would it fit. I ended up using 2.5" and I had to cut a little bit of sheetmetal. Radiator is wider? Don't know.

Anyway, the whole setup set me back maybe $15 and it works just fine. The purpose to prevent water from getting sucked into the engine. Doesn't need to be all bling bling.
The top part comes off. Get to a water crossing, stick the "periscope" on, and your good to go.

I thought about going with the ARB style, but it sticks up way too high. If they made one for the ZJ, I may have bought it though.

One of the guys in the club made a nice snorkel for his XJ. Used exhaust tubing and routed it up the A pillar, similar to what the ARB does.

I really like this idea. Was just recently lookin at mine,(4.0) and had not quite figured out what I wanted to do .That answered some ?? for me. About the snow thing, I'm thinkin maybe a cable switch setup, like the old GM functional Cowl induction hoods had. If and when I come up w/ something I'll post it.

Ok we need to have a contest of who has the ugliest most ghetto intake. Why because I would win. I have run this for a while and had some spare time on my hands and decided to post this for anyone who might be interested. These are before I had it on the Jeep. I will get more and put them up later. It is super ghetto. Ok basically it is a cheap ricer autozone filter JB welded to a plastic ring which is clamped to 3" PVC. The PVC is then attached to a 3" to 2" sewer adapter I picked up at Home Depot. Then the 2" side of the adapter is JB welded to the air hat. It is ugly but it works and I like it. It cost me a grad total of $35. 25 for the filter and 10 on all of the other stuff. I plan on making a heat shelid for it after I tear it back out of the Jeep. Anyway here are pics

Hey, bumping an old thread, (don't shoot me)

I just came across a thread for a cowl air intake.

Anybody see a problem with a setup like this on a ZJ? I looked and there is plenty of room in the passenger side of the cowl.

I'm thinking rain could be an issue, but not sure.

http://ericsxj.com/intake/5071.jpg

ELLLLLIOTTTTT
11-05-2009, 02:29 AM
That's a pretty cool idea. Do you have to worry about water getting into the cowl area?

FortCollinsZJ
11-05-2009, 04:30 AM
Thats my question, Elliott.

It seems like the cowl drains very quickly, but I am concerned in an instance of an inordinant ammount of rain watter flooding the windshield and collecting in the cowl, and then flooding the filter. Upon further inspection, the bottom of the windshield (under the plastic cowl cover) there is a lip that will help as a gutter.

If the hood were to ever be under water, the engine would begin sucking in water, lets hope it never gets that deep. :D

Here is what I got done tonight, it seems to be working alright, there is a loud swish noise when you first turn the key, but then all is quiet after the innitial gasp.

I used a 3" holesaw to make the hole in the cowl wall, then widened it out to fit the 90*. I will likely buy a good piece of flex tube to go the entire rout, from hat to filter.

As you can see I turned the airhat 180*, it worked perfect and doesn't interfere with the throttle cable. I also cut the cowl cover in half, making it much easier in the future to clean/inspect/replace the filter underneath. This way the wiper arms don't have to be removed EVERY time. PITA, those arms.

We'll see how it works in the long run.

rstrucks
11-05-2009, 10:48 AM
I wouldn't worry about enough water getting in there to cause any problems. That's where I have my ARB compressor.

Like Maxx said - what's the reason for stashing it in the cowl? It is isolated from engine heat more I guess.

11-05-2009, 10:53 AM
I've seen it done on an XJ, not a ZJ though. I'm sure if you just keep the part where the cowl drains unclogged, then you'd be fine. I've never had a problem with the cowl having standing water in it, you just gotta make sure mud/debris doesn't get in it. Are you mainly doing this to get a true "cold air intake"?

SirFuego
11-05-2009, 10:56 AM
That would be a nice "sleeper snorkel" since it bumps the intake quite a bit higher from stock. I got my turbo city intake to make room in the engine bay since I planned to cut out the stock intake area, but I still need to relocate my battery before I do that.

Even though I try to avoid mud, I've been known to lead a group at a small park near us (because I was the most built and could be the "guinea pig" for some obstacles so folks could avoid them if I had problems), have no idea where I was going, and dunk my front end in deep mud/water accidentally. It's nice knowing my intake is tucked up and away with the Turbo City intake. But I like the cowl idea better since it's better shielded from the engine heat.

BigClay
11-05-2009, 11:13 AM
My jeep sits outside, and that cowl area get caked with leaves, pine needles, and ither debris, so I would just make sure the filter stays clean. Maybe get a pre filter that you could take off, clean, and put back on.

As for why someone might do this, I plan on using the stock airbox location (I have a 4.0) for a second battery eventually.

K&N (and probably other companies) make outerwears for filters that are water resistant. It would help a lot in this situation where you would want to keep the filter dry in a place it might see water.

I def like the sleeper snorkel idea. I may have to try that. It might suck a bit when you have to clean the filter but I doubt it will get dirty as quickly. Heres my current setup. 3" id sewer pipe k&n and a $30 elbow.

I did it mainly for a CAI, and also because it freed up so much space! Tons of room for a second battery or compressor, or a small toolbox. Not sure yet.

I added the K&N prefilter (bag) to my K&N filter. Eliminated large stuff, also water is shed by the bag. Only the truely fine dust goes through and is caught. Also somewhere I read a test where a guy ran the pressure drop with and without the bag and it was essentially zero add (provided the data and the picts to prove it).
