    CAD/CAI for the DD

    To be honest, I don't know if anyone has come up with this yet, but I always wanted to get a CAI without the worry of sucking up water if I ever had to drive in the rain. I wanted something that could be easily disconnected at will, and without having to move the air filter, or use any tools to do so. It would also be something anyone can put together with a few simple tools that I'm sure most of us if not all of us have access to, as well as being a design that requires little to no modification to the body or frame work at all. And I think I have found a way to do it.

    I prefer to call it a CAD for Cold Air Duct for the reason the filter is in the factory location, but still sucks in air as cold air intake.

    First I used a $10 extend-able aluminum tubing from Home Depot to get and idea of the best way to route 3-4 diameter piping to the air filter, and the overall length of the piping.




    Made a custom sleeve from 2 slabs of HDPE plastic cut to shape to fit over the bumper inlet.



    Got all the intake hardware I needed from Spectre Performance through my local Pep Boys (cheaper than ordering through their website for me), and got a Weapon-R bottom feed coolant tank to make room for the larger 4 inch diameter flex tubing. I decided to go with 4 inches do to the air resistance that comes with the unavoidable 4 90 degree turns I had to make to connect it to my stock intake.




    All of this can be done for about the same or less the the DNP Intake you could buy from 3SX after shipping (apparently they stopped selling it). You can use it various different ways thanks to some of the Spectre products that I have never seen anywhere else, so just about anyone should be able to do their CAI based on their needs from it. This design was inspired by the custom CAI design I saw in Eric's car seen on 3SX. The only thing left to do is get the car on a dyno someday, and see what the difference is. The only results I have is from driving the car on the street, and though small they may be, there is a difference.

    There are good cars that get you from point A to point B, and then there are great cars, that get you into trouble.

    That looks cool. I'm wondering since I already have a short ram intake will a cold air wall/box benefit me in any way?

    I was looking at these two.

    You are not going to see any significant gains with intake mods on a NA.

    I suppose the more enclosed box could possibly do about as much as the stock airbox, but all the air is still coming from the same place by itself. I'm sure it could do some kind of good for you with the CAI/CAD, but you wont really notice it any more, if not less than I do in trying to keep the whole thing sealed.

    Not sure if you're replying to me or SOHC, but I already said that it's not much. I'm just curious to see what it is doing for me.

    Its a general response to the whole thread. You are gaining almost nothing.

    I feel it does something to make it worth while, when you compare it to everything else out there for intakes.

    I have had a true cold air intake and it does nothing. I ran at the track and ran identical times with a CAI and with a stock intake with an open element filter.

    I run a cold air intake on my car...only helped in summer stop start traffic, instead of going to the front of the bumper it squish's down beside the radiator and sucks the pre pressurised air from the front air dam(in theory)

    I can see why you wouldn't have seen much if any difference on the track, because it really is a VERY small difference. However, maybe the reason I am seeing a small difference and you didn't, is because I have done something different than putting the filter down there. I have yet to see anyone make any adapter to catch the air flowing through that area of the bumper. Maybe it's the amount of air that you can get in there, more than the temperature since our cars are computerized to adjust to the temp differences, and may not run as hot as the TT cars do.

    You are still not feeling a difference. You are not getting more air than a CAI would either. Its all placebo.
