DIY Mod: "Cold Air Supply"
). I have no idea what this will do, and I'm expecting nothing frankly. However, for $60 and having something to to do one weekend, I'll give it a shot. I won't be doing anything permanent to the car... and who knows it might just help. The OP is reporting lower temps with his ram air style version. I'll be sure to post #s before after as well as document what I do to the thing. Any great DIY mod starts with one person playing around while everyone else tells him he's crazy, lol.

How about a Y connection were diver side connects ramming air through the front and the other side of the Y connect the fan either sucking air from the bottom or from the passenger side. (would it need some short of flap so you do not send air out the dirver side while on low speeds?) So when you are idle or cruising at low you have plenty of air from the fun but when you are at highway (or faster) you take advantage of the natural flow. (how do we make the flap so the dominant flow blocks the other passage?
I do not think we can fit 2 tubes coming up to the intake.

Yeah there are a few possibilities. I think I'm going to try just a very straightforward fan to intake area setup and see how it works. I'm not sure how much air that fan can push yet, but given what its made for, I'm expecting it to be pretty good. Depending on how things work out, I might try and get more elaborate. My main concern honestly is space. The last time I peeked around under there when I first had this sort of idea last year, I wasn't seeing much space to work with. At the time I was looking to do a ram type setup like you have however. Since the placement of this fan is more flexible, maybe it'll be easier to find some routes for the hose...

Ive had a spare blower in my shop for months and ive wanted to do it for a while but just havent found the time.
You might not get as much air flow as your hoping though. Ive never really felt the air flow from the blower so i cant tell but i know i can hear it running over the 350 in our boat so...
Yeah I have no idea how much flow that thing puts out. I suppose I could carry it down to the Jeep and touch the wire to the battery terminal to see how fast it goes. Given the size of the motor in it and the fan blades, I think it'll put out quite a bit of air for its size. Whether or not thats enough to drive an appreciable amount of air through 2-3' of 3" hose remains to be seen though. I'm also not sure that volume will matter as much as temperature in this case, but also its hard to say how turbulent that area is when you're driving. I suspect that intake area gets very little fresh air given the placement and the sad hole in the fender where the factory airbox was attached. The ambient temp on the Aeroforce is always a good 30-40 degrees hotter than outside, and then the intake temp is 30-40 degrees hotter than that.
I'll definitely attach the hose to it and try it before I attempt to install anything. I have seen other types of fans that this could work with, and that probably put out more flow, but this one was cheap enough and in the right design to prompt me to try it finally. Other than the wiring, I don't envision needing anything to install this other than a handful of long zipties.
I bought a switch, inline fuse holder and some 5A fuses yesterday, and ordered a couple feet of hose last night (that aircraft stuff linked earlier). Total expenditure so far is about $70, and I think I have everything I need except maybe a 3" hose clamp which will cost hardly anything. If it has any positive effect, this will be a good addition for $70. If not, hey at least I'll be entertained for a day for $70.

Yeah we'll see how it goes. I'm not expecting much, but you gotta figure any blast of air at the intake that comes from anywhere other than under the hood, should make some difference. I just have no idea how much...
BTW, Kenne Bell did a similar thing for the air intake that feeds their supercharger. Me personally...that setup scares me. Water splash into the air filter and all.
Anyway....Air Supply...they sing Making Love Out Of Nothing At All. Just sayin...
