The only way I can think of using ducting would be from the lower grill to the original intake opening. That wouldn't be too difficult. I made sure the box took advantage of the other hole (the one on the engine bay wall that goes straight into the fender) just in case it needed more air, or if water got in the box. I've had bad history with water.
It's the RS kit with the Greddy. The OEM might not be low enough.
Damn, man. That is talented stuff. You ought to make some in your spare time for some of us lazy no talented types. I for one would be wiling to make it worth your time. Send me an email and we can negotiate.
I built it out of scrap plastic, about 1/8" thick. It's very light. I think the filter weighs more than the box. Everything else comes from Home Depot. Bolts, flat black paint, weatherstripping and cement. Even the O-ring that seals the intake piping to the box was improvised. It's a clean slice off a black foam coozy. Everthing came to under $10.
You can buy a rotozip just about anywhere. But I bought the Craftsman brand from Sears. You get a circle cutter, mitre base and more for $59.
newbie here, but what are the benifits of having your intake filter boxed in?

is there anything bolting it to the chassis? or is it just sitting there? where did you get the plastic to do that? if i can get the plastic....this is going onto my todo list!

hot air from engine bay doesn't go into the intake. might also want to find some way of insulating the intake tube. that'd pretty much eliminate heat soak. well, a hondata im gasket would finish up the heat prevention.
ok, that makes sense. but isn't more air better than less air, reguardless of hot or cold? as i see it the only place to get air would be from the duct below the air filter.

I guess the thing is that there's an Air Intake Temperature sensor that measures the temp of the air you're sucking in, and I believe that if it picks up hot air, it'll retard the ignition timing, resulting in a slightly greater low end power, but you lose high end power, which is what matters more when you're trying to race when you push your car hard.
Besides, the colder the air, the more dense it is. It's high school physics class. If you have 1 cubic foot of cold air, and 1 cubic foot of hot air, there's gonna be more O2 particles in the cold air. Your engine's gonna be making more power out of the cold air for the same reason, that there's more O2 in the cold air than in the hot air.
i actually have something like that, but it's hella ghetto looking. It's a piece of sheet metal (galvanized nickel), and it covers about 1/3 of the filter, the top part so to block out the hot air. It's basically modelled after the Injen Heat Shield on their filters, but it doesn't cover as much of the filter as theirs.
To get more air, I used dryer piping and ran it from the lower front grill of the car, behind where the fog lights would go (I don't have foggies), up where the stock resonator was (I had to take it out, obviously), and where the opening to the stock air box was. This way, the faster I go, the more air is being pushed up against the filter, and it's outside air, not the hot engine heat-radiated air. I can feel it on the freeway, esp on a cold night, but I don't notice any low end-gains over a normal un-heatshielded short ram intake.
I know it works because before I did this, after driving, I'd pop up the hood and the intake pipe is hot to the touch. Now, it stays nice and cool. The cold outside air probably keeps the intake pipe cold as well, neutralizing the heat from the engine bay. So that must work...
But Prelude SS White, that looks really really nice... If you can make a bunch of those, I'm sure people would buy them. Heck, I'll pay $30 for one. that's $20 profit for you right there... Figure a lot of us would like so too so....
