question on cowl snorkel write up...

i was interested in doing the cowl snorkel mod that someone outlined on here. seriously looking into it.

but i was thinking, how much more clearance are you actually gaining? the airbox on my jeep is on the front right fender, with the opening facing up. placing it in the cowl maybe gains 6 more inches right? or is there something i'm missing?

your not gaining just 6inches, your gaining the height of the pipe over the hood and over your roof.. your gaining as far as the air opening (top) goes. do you understand what i mean? Like in the pic he can go as deep as the red line

But if you go as deep as the red line, your looking at some serious problem, loosing control of the jeep and probably getting taken by the stream...

what your missing is that water crossings and streams usually involve dipping down quite a bit to actually get into the water. often your headlights will become submerged, but once your in the stream, water will be up to the doorsill or turn signals (about 3-6 inches below the stock horn).

if you're cowl deep in water, you've got bigger problems than wondering if your engine is breathing, like how you're going to get out of the jeep so you don't drown.

if you're headlight deep in water, then you should be worried about your engine.

Don't forget about the benefits of drawing cooler air into your engine with using a cowl snorkel. Power and mileage might be slightly better.

maybe i didn't state it clearly. i understand a REGULAR TOTAL SNOKEL... i mean the semi snorkel setup people are doing putting an open air filter under the windshield wipers. doesn't it get wet there every time it rains or anything also? those vents allow rain and everything in....

Unlimited04 hit the nail on the head. When you drop in to water the front end of your Jeep will submerge, then when you get you butt-end in you will sit level again --think of driving down a hill when you reach the bottom, you nose down until you get level again -- its the same thing, except with water. Moving the intake back from your grill makes it harder to get water into the airbox

And yes water gets in, but there is a drain for the water in your cowl, otherwise the water will drain into your Jeep through the AC/Heater intake (if you didn't have the cowl intake). The cone filter doesn't sit directly under the cowl vent so it doesn't get directly wet from rain/water, and in most cases, from what everyone as written up, it actually stays VERY dry, the drain in the cowl apparently has a good amount of flow to keep it dry in there.

NOTE: I have not put a cowl intake in my jeep, yet.... That is actually this week's project, I've been reading up on any, and every thread I can find on it, on this forum and many others. This by no means makes me an expert (or even close to it), but it seems like a common queation about this set up, one that I asked myself a couple times.

If your going to do it, go for a Hummer style setup. You'll love it.

If you are worried about the filter getting wet, do the buick or windstar (or one of the other options) airbox mod. I have the windstar which has the airbox under the hood so all that goes through the firewall is the trumpet. It is off center to the vent and intake is perpendicular to the way water would come in. Its also a couple inches off the bottom of the cowl, so the drain (which is pretty big in my 06) would have to clog and cowl would have to fill. Water may actually drain through the AC before getting in to the trumpet. I even went ahead and put on backward facing cowl scoop covering the vent but that was overkill.

if u are going to do it, do the hummer style thats what i did and i love it first i tryed the filter sitting under the cowl at the one end away from the vent. but the only problem was i was out of the country for 35 days and came home to my engine being full of water because the drain was cloged from crap and heavy rains added up to a hydro locked motor kind of scary to come home too. so i thought it was time for the hummer snorkle and i love it dont worrie about anything anymore flying thru big puddles here in fl. look at my past replys under my user name and u can see my pics and my set up with the real 4.5 inch hummer snorkel cap
