cowl intake vs snorkel

right on

Odd question:

Since you are now pulling air from the same area where your cabin blower pulls from, do you notice a difference in airflow from inside the cabin while driving. Seems like it should be fine, but that would be an interesting side effect.

The hose from the valve cover to the airbox must be connected. Do not discard it.

No difference at all

cool, however it would be kinda funny to see the AC flow fall off under hard acceleration.

I have (in the past for my bronco) designed an intake system that incorporates a 4 in float ball inside of a sealed airbox. As air is pulled in from the bottom it moves the ball and allows air into the filter. If the opening sucks in water, the ball would float plugging the 3 in opening leading to the air filter box.
It restricted air flow, but,

it was contained inside the engine bay, and would kill the motor before water even got near the intake manifold.


I'll see if I can find some pictures, or draw up a diagram.

ok, so I talked to my bride about this type of mod, and she was intrigued. Having re-read the install notes, and the anecdotal experience of having a smog referree completely glaze over the stock-looking install, I now do see the draw and wisdom in this.

plus the pic of the short snorkel stack on the dark colored xj is very understated and classy. I like that.

Anyone have pics of an "extention" installed a la Humm-v deep fording kit? I'll bet it'd be easy to install and seal with a rubber coupler and hose clamp. You could reinforce it off a roof rack @ the top of the extension for stability.

That is a good consideration but in the real world it equates to about what it feels like for two people to breathe inside of a compact car. If it was a completely sealed area, it might be a problem but there's lots more air where the first breath came from. :thumbup:

I thought that the A/C cut off on WOT anyways.

 

[wolfpackjeeper]

well, the blower motor output then.

This is getting to serious for a random off thought that is kinda unimportant anyway.

The compressor, yes, but the electric blower doesn't slow down.

What a great thread. muddeprived, I love the clean look and the functionality of the taller intake. I'm in Florida and don't plan to ford a deep river. But in the land of thunderstorms and hurricanes where any street could become a 3-4 deep river, you never know. Now, how to combine the cowl intake and cowl snorkel so I can loose the stock airbox and gain a few square inches of underhood space for a second battery...

 

[CromeY90]

that would be cool

i'm going to be picking up a k&n apollo filter (http://www.jegs.com/p/K-N/K-N-Apollo-Unique-Universal-Air-Filter/1216658/10002/-1) do the cowl mod, i wheel with nosigma(hi john) on the same trails. i doubt i'll go in water deep enough to cover the hood and cowl.

Great solution, except for the K&N filter. Apparently K&N purchased the product marketing rights from Apollo......

 

[RedChuck]

does anyone make the same sized filter to use with the Apollo or are we stuck with K&N

 

[wolfpackjeeper]

I am sure dryflow or someone like that makes one. If you look real hard I bet that there is a stock one that fits. Maybe an accord or mustang.

Spectre Performance makes an inline filter kit, and also offer cowl intake kits for the TJs and Renix XJs. There's a thread in Street & Perf with the inline unit- there was a brief shot of it on PowerBlock yesterday while they were fabbing up a Spectre intake kit on a musclecar.

Another option for inline filters, although I don't know if Spectre is a great company (I have their 3" airduct for a cowl intake, but until I found the link on here, I only knew them for their selection of ricer parts at AutoZone.)

I like the snorkels....that come out of the cowls.

Mine's designed to be removable for winter.

This would look pretty cool sticking out!

 

[CromeY90]

that totally would

 

[muddeprived]

Where do you get something like that? I wouldn't mind giving that a try.
