TRUE Cold Air attempt
There is only one small problem with this venture, when its 112 degrees out, there is no such thing as a cold air intake. Not trying to be an ass in any way, but does anyone really feel that their Jeep runs better when it is say 30 degrees out? You will have less restrictive flow from an aftermarket intake, but the gains are hardly worth the price. I have seen some pretty cool functional hood scoops on a couple Jeeps on this board, have you thought about that?
I getcha...but I think I missed it-- You're gonna have to snap a pic of yours as mine does not look like there's enough room to sneak anything around by/to the grill....
you mean running it straight out towards the radiator and then down to BELOW the radiator? hmmmmm interesting idea

.... Just trying to make the most of this jeep! The hood scoops are awsome but running the duct work is still gonna be an issue...
why dont you order a K&N replacement filter and connect it where the stock box is and open the front of the box like the aftermarket systems. You can literally recreate the aftermarket setup for a fraction of the price by using the same concepts. Use the plastic tubing and ruber 45 to connect to the throttle body. You have most of the parts.
THANKS VBS! I will look tomorrow when I have more light!
Have you considered a modification to the hood (like the J8 snorkle), or even one around the lower passenger windshield area? The J8 snorkle inlet is kinda fugley, but I think a modest intake port just through the cowl which routes completely underhood could be cool.
The issues I see with the intake area are obviously water and dust on the trail. Even puddles on the roads might be risky, and on the trail/dirt roads you'll be sucking air from the worst possible area. One final consideration is in very hot temps the air charge near the pavement is hot, this has long been a issue that performance car people have had to deal with when they have "bottom feeder" intakes/ram air kits (but yours is up a bit higher than what they typically have).

Someone on the board took the front amber turn signals out and relocated them.
You could run a duct to the pass side turn signal light location. They'll be enough tubing and a decent bend that water will get in but will have a tough time making it up to the box.

Using my scangauge I can see some very elevated temps over ambient. If you are seeing 112 on the dash you may have temps over 150 entering the air intake under certain conditions.
I've watched mine for months now and the highest I've seen over ambient after driving over a mile is 48 degrees F. Most of the time the delta is from 12 to 20 degrees. While the true HP increase you will get from the engine will be small, this project will benefit the JK.
Post the secret when you discover it.

And THANK YOU! You just helped kinda prove my point about the heat build up inside the engine compartment and its exactly why I'd like to find something *Cheap* to route around the problem.
I'm thinking about going and hitting up a couple of smaller muffler shops with tubing benders and seeing if they couldn't make a complex bend or two on the cheap............
Got a worldwind plate full of crap to do today that aint involving the jeep: then gone for a day....will most likely be Monday before I can resume this project...... but PLEASE- keep the suggestions and ideas coming!
Not trying to be stupid here but - how about running a 1" rubber hose from the A/C duct to the CAI tube . Just a thought. I know it defeats the purpose of saving gas because the A/C is running - but wouldn't it run stronger with cold air?
