Nice BAF filter, swampthing... is that an AFE unit??

That was what I was talking about if you were concerned about airflow burtman sells an Escalade style fender mesh vent thingy that could be made functional with a little metal work.

Hmmm...This is pretty interesting.

I wonder if you could use a small pipe if you had some kind of booster to force air down it.

Cowl:
"The portion of the body bounded by the front fenders, the base of the windshield, and the rear edge of the hood."

Basically the engine air comes from the same place as the cabin ventilation air does:


I found I got way too much dust and dirt in the air filter with the end of the snorkel above the tire, even with an intact plastic wheel well liner.

And as far as the intake being not a lot higher, that is true (it is 10" higher), but now I would have to have a wave of water roll up over the full length of the hood to fill the cowl with water. And also, moving the intake back (about 3-1/2') helps a lot as you most often hit water when dropping nose first down into a water crossing. Sitting level, the water may only be up to the bumper but drop the front end off the bank and you can stick the whole front end under water for a few seconds. The stock intake (22RE) is next to the headlight and it is easy to get water in there.

It was like that many many setups ago lol. That's a AFE 20-40044 filter (referenced off a wix 42790). Then I went with a afe torque tube instead of the stock box bendy tube. Now I have just have twins.

Any issues with water splashing over the hood and filling the cowl area? Is it drained well?

Haven't run into that problem yet, would take a really deep crossing to do that and then I would think other things would start getting wet. As noted on the web page, I did add drains under the air intake (circled in red in the above image) so that if any water does get in, it'll drain out before getting into the intake. I did hear of one guy who runs a similar setup but he sealed his intake passage up tight. One afternoon he was parked on a slight side hill when a brief downpour of rain hit. Enough rain fell to full up that downhill side of the cowl and when he tried to start the engine the water got sucked into it.

I doubt the that latter situation caused damage, would you concur?

I like this "cowl snorkel" it doesn't change the factory look, doesn't add aerodynamic drag, yet is almost as practically functionnal as a ARB Safari Snorkel (albeit perhaps not for dust)..

I wonder if the engine would start if there was snow piled up over the cowl? Curious.

I think the guy had to pull the plugs and blow the water out of the cylinders after than rainstorm. Don't think there was any permanent damage, though.

Not sure if I have run into snow piled up on the cowl, but that is easily brushed away before starting the engine.

I wonder if its even possible to damage an engine at idle by hydrolocking it.

heres mine, planing on redoing it. but it goes into the cab behind the fuse panel. i'd like to raise it like 4crawlers

Matt16

You've just made the only in cab vacuum cleaner. Brilliant.

akaphilly

well its behind the fuse panel, then behind the kick panel. with a atv prefilter. i'm not to worried about being a vacuum. anyways didnt 4crawler say "Basically the engine air comes from the same place as the cabin ventilation air does" whats differnt about mine?

akaphilly

well if other people can think of it obviously i'm not the first one, like u stated before. and FYI.. i dont hear any intake sounds. unless i floor it. and its on my daily driver.

Matt16

When you break wind, does your engine power up?

I was just kidding about the vacuum cleaner, although I might be tempted, when bored, once in a while to deliberately drop McDonals wrappers on the floor when driving just to see if the intake would hoover them. I was picturing the intake coming out somewhere visible and accessible.

corax

I've been thinking about running my intake into the cabin for a long time (can't run safari snorkel because of my Hanneman fenders), but I may have to reconsider and take a closer look at 4crawlers idea - but I think I might just leave the original cowl drains open (rust prevention)

My drains are still open, I just used a couple of small tubes in the larger hole and sealed up the rest. This was both to allow water to drain out and yet keep as much dust as possible out.
