How would I go about building a cold-air box for my S4?
FC3S.org only has a write up for an S5 and the link given for the S4 buildup doesn't work. Anyone? And I refuse to spend $125 for a Mariah box.

Do as he said but you can just go to home depot and get some sheet metal, trace it and cut it out with tin snips. I did it for mine. While your at HD go to the AC section and get some foam to go on top to to seal it against the hood and also get some aluminum tape for the corners.

The Mariah heat shield (that is NOT a cold air box!) is a good design, it's just ridiculously priced. Use it as a basis for you own one. Once it's in place you can have a think about how you're going to duct some cold air into it.

I made mine starting with the cardboard mockup and then finished it with aluminum. I used one piece of aluminum bent and riveted together. The side of the box facing the engine has some reflective type tape to help keep the box cooler on the filter side. Just plan carefully and take your time. Its fairly simple.

I need to take some good pics of my set-up so you guys can try and copy it. I have went through about three different designs and the one I have now has to be the most logical way to keep cool air going to the filter. I really noticed no difference in power but the thought of it makes me feel good.

I used a thin sheet of aluminum fron true value. I'm gonna make a new one out of a thicker sheet; but cutting it with snips is tough. I tried air cutters but they just chewed it up. I'll see if I can get some better pics sometime soon. I also have a 2.5 inch tube running up from the front bumper that goes into the bottom of the bos to supply fresh air. It has a 4 inch tip to catch a lil more air; then runs through that lil hole in between the radiator and the frame, then up into the bottom of the box where I added a 60 degree end piece to direct the air at the filter. The hose doesn't always go exactly where you want it to so getting a few of those plastic plumbing pieces will help get things flowing like you want them to.

Who killed my pic? Nothing I hate more, than that damn red "X"
Fixed!
Oh; and I love the strut brace. Deffinitely worth the extra dough. It stiffined up the front 10 fold. A freind of mine has just a regular strut brace and he said he could barely feel a difference, but I felt a huge inprovement. I have a vert so that may change the effects of it though.

Seriously, water spray is not an issue. It probably wouldn't make it up the duct and even if it made it into the engine, it will do no harm. It's only large amounts of liquid (as opposed to droplets or a spray) that should be avoided.
