What would you like in a snorkel design?

In a few days, I hope to complete an interesting project – replacing the coil springs with air springs.
When this will be over and thoroughly tested off road, the rest of the wish list will follow, a snorkel is part of it.
I've been following this manufacturer / target-group exchange with much interest, and appreciate the idea of a short snorkel and the option of lengthening it.
Two points which I haven't seen here, sorry if I just missed them:
RR,
In addition to (static!) dyno check, I'd check the actual air flow next to the snorkels' intake.
It's quite easy to do. Narrow strips of soft & light cloth, attached with duct tape, will make the air flow visible, at different speeds.
With the Jeeps' aerodynamics of a brick, the short snorkel's location might be a problem – from no air pressure while moving, to negative pressure at the intake.
Please convince yourself, then us, that the flow is OK... Pictures will be welcomed and appreciated.
Another point is possible excessive heating of the air along the black, un-insulated channel under the hood, when the Jeep is standing (I'm thinking of desert conditions).
Once these two issues are OK too, my Jeep has a good chance be the first to "wear" it here :-)

We can see what can be done but just so you know... One reason the low intake is mounted off to the side has a lot to do with air intake and the low pressure area you speak of. As for the intake tube location and how it affects the inflowing air temp??.... That has also been looked at and was my biggest concern during development. Prototype testing showed high temperatures at the manifold but constant tube temperature of about 81-85 degrees. this is a very short run so very little time for heat to transfer from the tube to the air as it heads into the air box.
Remember, you will be pulling cooler ambient air.
