How to build a true cold air ram intake?
I have the intake adapter with cone for the NA motor, but i want to make a true cold air intake. I was thinking about goin down into the brake duct. Dose anyone know what piping or where to get the piping to do so? and how to get down there to the lower bumper? Thank you.

Well, forget ram-air.... but, CAI is relatively easy if you are creative. If you don't want your washer fluid bottle, its even easier. But given you live in washington, you probably want to keep your washer fluid bottle.. SEARCH

search for "prelude" in titles and you should come up with a few cold air intakes. some peeps on here use prelude cai pipe to make theirs for the fc. search for DDUB too he originally did i think.

A true ram air intake employs a divergent duct to decelerate the high-velocity intake air, increasing its pressure, creating a small amount of boost. In this respect, ram air implies a pressure gain, but in technical terms "ram air" can also simply mean that it takes in the relative wind with no pressure gain. Nearly every car and aftermarket part manufacturer uses this technical definition because their ram air hood has absolutely no pressure gain.
A true cold air intake employs a chilling system (CO2, N2O, dry ice, etc.) to cool the intake air below ambient. If the chilling system is placed downstream of a supercharger, it is sometimes called a "one-shot aftercooler" or a "supercooler".
Did you really want to buld a true ram/cold air intake, or are you just trying to piece together a fancy looking intake like you see in car magazines?

I used a newer, not sure which year, Jeep Grand Cherokee intake pipe and it works great. It even looks somewhat stock. It fits right onto the AFM with no modification, and using a few plumbing parts I connected it to the filter. I just cut a hole in the fenderwell and ran the filter down into the fresh air stream of the brake cooling duct. I relocated another washer fluid res. near the charcoal cannister. Definately better than stock.

Most other people with an education and experience in this type of subject actually have a life and don't contribute very much to automotive internet forums, lol.
Anyway, my post was intended to prompt the original poster to fully evaluate his goal. It is not very easy to get from here to there if you don't know where "there" is. I don't see anything wrong with a fancy looking intake, just as long as the buyer/builder does not confuse it for a fully functional intake. As you may have gathered from my first post, a fully functional cold air and/or ram air intake is probably not very practical for most forum members.

Keep in mind that air density has two primary components: temperature and pressure. Many people forget about pressure, and they design a "cold air" intake tube that is so convoluted that it causes pressure problems.

Seriously, I agree that's one of the best lines I've heard this year!
