COLD AIR BOX for 5th Gen

We all know that the current crop of intakes, besides the ones you have to cut(CAI) into the fender, draw hot air from the engine: Thus robbing low end power. Who would be interested in a cold air box, which fits around your current intake system that would allow you to draw cold air from the front of the car. It would look similar to this:

I will have prototypes available soon.

Re: Re: COLD AIR BOX for 5th Gen

Should make less noise than current intakes because your intake will now be in a box with a large diameter snorkel sucking in cold air. No dyno yet because it is still in development.My goal is create a high quality thermoplastic or CARBON FIBER COMPOSITE box that draws cold air from the front of the car- not from the engine bay. COLD AIR IS GOOD!! It will look very SLEEPER under the hood. It will also make your max easier to sell down the road - if you do so.

Check out my latest heatshield design. Look familiar?

how are u makeing this?? are you useing the stock air box as a guide?? or are you make'n it from scratch? i made one from the stock air box and it works.. but the stock air box looks ugly.. well its sounds like it a good idea.. good luck on the developments..

It will look nothing like a $4 piece of heat absorbing sheetmetal ( with holes on both ends. I will make this unit from a clean slate using only the best materials. It will be "COMPLETELY SEALED" from the heat from the engine compartment. I am leaning towards carbonfiber due to its heat resistance. It will pull air from a Ram-type airdam. I dont know if it will create a ram -effect. But I do know it will pull colder air FORCE-FED FROM THE FRONT OF THE CAR. i AM MEETING WITH THERMOPLASTIC /CARBBONFIBER FAB/CNC people friday.

Good luck, but do you know what it costs for plastic injection or carbon fiber molds? 2.8 wagonloads of money. If you use plastic, you'd better choose a good type like 30%GF Nylon 6/6. You don't want ABS or Polypro. An automotive engine compartment is not the most comfortable place for a plastic component to function.

Goodluck with that. I doubt it will perform any better than just finding a cone intake that can be installed in the stock air box. Easy to do. The stock intake tract is about as "ram air" as you can get.

That sheetmetal on my heatshield disapates the heat quite well. It's never hot to the touch. Don't knock the ssetup if you have no experience with it. Also, there is TONS of air flowing around the filter. If you would have read my post, you'd know there are a couple outside sources of air feeding the filter. Oh and it's not open on two sides. It's only open on the driver's side.

Make yourself a measuring device. Fine the smallest tubing you can tape an open end of the tube at the desired location, magically run the tube into the car where you make a bend (like an exaggerated sink drain/plumbing)....add a bit of H20 and go for a drive. Suction will lower the water level and pressure will raise it....measured in inches you have pressure in inchesor water which you can convert to inches of mercury or psi(i think it can be converted to that)

Re: Re: COLD AIR BOX for 5th Gen

still in the works. I tossed my stock box . Maybe that was a bad idea.
Oh well I want to build something custom looking.

Simple HD project.

Sheetmetal, a rivet gun, (2)2x4 piece, (2)low profile hinges, plexiglass, hex sheetmetal screws(8mm), circular flashing for duct. 3" drill-saw bit(PR CAI owners know what I mean.) (4) 10mm nuts and bolts, 3 ft of 1/4" thich weather stripping.

Sorry I won't go into insane details, but hopefully you guys get the idea.

The Jig: 2x4 wood, hinges, and sheet metal screwed down to provide better leverage to bend sheetmetal in straight lines.

Measure filter, design around filter. Bottom panel should be done first to get original mounting holes for stability of box. When bolting them down, use silicone on the washer, to seal box.
Drill and rivet together 1/4" spacing of rivets, leave top open.
On the panel facing towards the fuse box and battery, cut an opening so the circular flashing for a duct can suck in air coming from the fenderwell...3" hole and line up MAF, mark holes, and drill.
To finish off, measure and cut plexiglass, drill every 1/2" and w/ hex sheetmetal screws, screw down. Don't forget to line the top w/ 1/4" weatherstripping, so the box is sealed.
Now you can see in, and marvel at what you've created.

I can do a full write up with pics if needed, cause I've already done this, and it took about 2.5hrs of playing around in my garage.
The box is loud due to resonance of air coming in. Hard to describe.
a pic?

Isn't your idea similar to this "http://www.weapon-r.com/airbox.html"
I thought somebody had already posted that they were in the process of designing a box like this?

I would be VERY interested in a "sleeper" look. Sounds like it may be a simular setup to my old stang baffle. If it could be mounted lower it will keep noise levels to a min until WOT which is cool anyway. Cost should also be a factor though, keep it resonable and provide some #'s and you'll do well. I keep watching the progress.

I'm VERY intersted in seeing a pic. I've been wanting to put in a cone or something, but I'd prefer to have the cold air without drilling.

$45 at HD and a few hours welding, and cutting and 1 hour to paint
Didn't you post a sound file of how this intake sounded. if i remember correctly, I heard it sounds sweet.

Any chance I could get a writeup/instructions and parts list on how to do this?

Thanks for the write-up. I'll give it a shot sometime soon.
