Cold Air Intake

[wncwheeler]

Im thinking about putting a cold air on my 360 and was wondering what peoples thoughts were on them?(if they are worth it) and secondly if you have one where did you sqeeze it in? pictures would be greatly apperciated!! Thanks Ben

I have never seen much of a purpose in one on a Jeep. I have always just gone with a 360 degree air element. Newer cars have a pretty sealed up engine compartment, but older vehicles get tons of air moving underneath the hood.

[DanHS]

FSJ's come with a cold air intake, the little rectangular hose that goes from the air cleaner to the valence behind the grille, there's supposed to be a plastic piece between the rad and battery for the hose to fasten onto. In fact there's a cutout for one on the driver's side under the coolant overflow bottle as well, which lets you make a dual intake setup. The difference between this stock setup with a good filter and a cold air intake with the pipes and cone filter, is this is already there (therefore cheaper) and your air filter can't get covered in mud.

I'm working on one, I'll let you know what I come up with.

I'm working on one for the deiselwag. Since all of my underhood AC stuff is gone, I'm going to tuck one back in the corner of the engine compartment and pull air from the cowl using the factory hole that was there for the AC stuff.

The problem with the stock setup is that its *VERY* restrictive. When I went from the stock setup to a 360 degree air cleaner is was a nigh and day difference. VERY noticable change in power. So if you want to use a setup like the stock one, you will need to change the air filter housing so that you dont have that necked dow section where the hose hooks up.

This is the ABSOLUTE truth. I couldn't believe how much more top-end power I gained after going to a 360* filter. :eek:

When I changed to MPFI I was forced to come up with a new way to route
the intake air system.
I combined a cold air intake with a snorkel.
I removed the air vent and ran 3" tubing between the fender and the vent with a 90 deg bend where it exits under the hood hinge.
I welded a 3" tube to the filter box (ammo box) cheap and watertight!
The box was connected to the vent tube via 3" rubber elbow.
I think you can get an idea from the pics.

Somebody on here ordered one off of Ebay for a Dodge Ram truck... there were pics a couple of months ago... you might do a search if you're interested.

[Mahamotorworks]

The ammo box under the hood looks awesome. If only it held ammo too.

[Dr.E]

You gave me an idea!
Well, how does 50 rounds of 44Mag, an auto pistol and 12 rounds of 7mm Rem Mag for starters.
Filter Only:

Filter plus gun&ammo

SEE there's never an idea that can't be improved upon!

[PlasticBoob]

LOL! Chris really does have one of the coolest FSJs around! Can't wait to meet ya, Chris! :D

[Dr.E]

Let me know when you want to meet.
Maybe next time you find yourself in Fulerton?
I'd be happy to share the details of the cold air intake system I fabed.
How did the WBO2 fair?

[ArmyGreenSexyBeast]

Dr. E, that is one pretty engine/engine bay. good work

[Mahamotorworks]

I like it a lot more. I plan to use Ammo Cans to hold some revocery gear and Emergency equipment.

'cold air intake' is usually the exact opposite. every factory vehicle (at least since the 80's) has come with a stock cold air intake. these "kits" they sell for a couple hundered bucks (worth only 20 in parts) are mostly all HOT air intakes!!! look at the design, they are open element systems that suck air in from the HOT engine compartment. we all know that HOT air is less dense, that is why you try to get COLD outside air. the open element air-cleaners will give you the most air, but again its HOT air, not cold dense air. it may be better then stock, but if you are going to shell out some coin on one of these 'cold air intakes', make sure it really pulls air from outside the vehicle.

the best setup would to be to use solid tubing to the stock inlet, but open up the diameter to accept a larger tube. also depending on the grille you are using (pig nose for instance) modify the grille to let the air go straight into the inlet instead of around it.

but remember, when you create an easy path for air to enter, you also create an easy path for water to enter!

[Dr.E]

Exactly!
X2 AL
If I hadn't widened my core support to allow for a wider aluminum crossflow
radiator and added a dual batery tray I would have done exactly as you recommended.
Now I get truly cold air and don't have to worry about going nose first
into water.
It is funny how many so called cold air intake systems are nothing more
than a tube with an open element cone filter all inside the engine compartment?
Not much room left over!, but she runs cool!

I wanted to try the cheap eBay Dodge 5.9 "cold air" intake, but I found a few things wrong. First, as mentioned before, it sucked in air from right above the pass. exhaust manifold, which makes me think the air would be hotter than even a 360* element would suck in (at idle and low speeds, anyway). Another thing is that the tube is only 3" in diameter, which might be fine for a 360 but is probably not good enough at high rpm for my 401. I'm currently playing around online with a modular system using Spectre components that have a 4" diameter.

How did the WBO2 fair? Oh I don't have a problem driving out there at all! I've still really busy, but things should calm down in a few weeks. The wide-band sensor is simply AWESOME, I have the majority of tuning done on my VE table. You can still borrow it, I think I have the thing running just fine on open loop operation. I just need to fine-tune WOT, and I believe I may be having some injector driver issues when I mash the pedal, but that shouldn't matter when I upgrade to MS-II. Keep in touch on the So. Cal. board, I still check it often! :D

[Dr.E]

Done! see your megasquirt thread.

[etjeep]

Nice clean install Dr. E! Thats a great idea. What filters are you using? all I saw was cartridges.

[Lindel]

Dr. E, where or off of what did you source the parts for the snorkel and etc?

[Dr.E]

The filter is( K&N) p/n KNF RE-0910 the wrap is p/n KNF RE-0910PK, purchased from AJ-USA,INC. Any shop that can do true mandrel bending can make the tubing for you. The clamps and rubber connectors I purchased from Air Flow Systems Inc. They have three locations that I know about, one in Portland, OR and two in WA. The ammo box is a 30cal ammo box available at any army surplus store. The snorkel end I purchased from ARB-USA sized for 3" tubing.
the manifold is a custom item I fabed and had sprayed along with the tube with bed liner.

[Dirtball]

The new Jeep Junkie has a really good cold air intake article...

[Lindel]

Thanks! I like the set up you have.

What did you fab the manifold out of? Aluminum?

[Dr.E]

I made it out of sheet metal and 3/4 bar stock and a section of 3" tubing.
(Yea a lot of heating,bending,welding,grinding etc...) Aluminum would have been a lot easier to work with, but you use what you have. I made it like a shell so if debris ever got into the snorkel I could open it up and clean it out. I also screwed the 3" tubing that goes down the vent area
to the inside of the manifold, and sealed with RTV. There is a gasket between
the two halves and one under where the manifold where it fits against the body.

Hi guys I am running one of these (web site below) with 4" hoses running to it. I noticed a pretty big difference from the open 14" element that I was running. Engine is running better and cooler. Cut the stock square holes in the valance with a sawzall to make them round and plumbed the hose to it with some HVAC duct. I will try to get some pics early next week if any one is interested.

Wooky,
Thanks for the link and ...............pics are always welcome here!

[Wooky1]

I will try to get some pics up next week. I am pretty happy with the whole set up.

[fulsizjeep]

Wow, that is a clean install Chris. Very nice! :thumbsup:

[my 2j20's]

Any reason why one set up like the olds did with the w30's?

I just got a breather from a mustang and thought that would work...taking it threw the fender and run the ducking along the bottom & down.

What engine is that off? Ford never made a 4V 5.0L V8. The current gen has 3V per cylinder. The old pushrod 5.0's were 2V.

Doesn't 4V also mean 4bbl occasionally?

[my 2j20's]

see them sold on ebay all the time, 79 to 85

4 barrel carb of older 5.0 Mustangs.

[Stuka]

Ahh yes. 4V can mean 4 barrel carb. I totally forgot. I guess I am to into new cars :P

[VonBoomenstien]

thanks for the ideas you did a great job. i just bought 2 ammo cans to try and copy you.

[Dr.E]

There are a lot of little details like notching the inner fender(for the ammo box so the lid will clear the hood when opening) and locating/cutting the holes, what you will find when you open up
the side vent area and how to fit the tubing etc...
If you run into any specific problems let me know and I will let you know what I did.
I do believe that there are much easier ways to route to the cowl, but I wanted/needed to locate the tubing where and the way I did for specific reasons. There is a member here that went into the cowl approximately above where the brake master cylinder/booster mounts. I saw the pics when I did a search for snorkels. There was also a pic of something like I did with no known origin so I just tried to copy the placement of the snorkel from that pic.
Lots of great info here and fine people willing to help!

[80wag]

Interesting thread guys, experiencing some mild vapor lock wheeling this weekend, I might ought to read this. One question.

What is the difference between a stock air filter system and a 360 deg. one? I thought the stock system had a round filter in it?

By the way cool snorkel and pimp motor setup. Impressive.

[mimmp]

Doesn't 4V also mean 4bbl occasionally?

Actually, the V stands for Venturi.

[Serious Johnson]

The problem with the stock setup is that its *VERY* restrictive. When I went from the stock setup to a 360 degree air cleaner is was a nigh and day difference. VERY noticable change in power. So if you want to use a setup like the stock one, you will need to change the air filter housing so that you dont have that necked dow section where the hose hooks up.

Really? I've found the opposite. I tried an open element filter I had lying around and got a small but measurable power loss compared to the stock setup w/hose. It certainly sounded faster, but the stopwatch said otherwise.

My 360 makes maybe 275-ish HP and occasionally hits 6,500 RPM. If the stock setup is restrictive, it must not be horribly so. I'd be interested to see how a better configuration performs, and there sure is some purdy work shown in this thread!
