I saw an Altima with a cold air box, courtesy of Kamski, and I was inspired to design and build my own. I bought a sheet of steel, tin snips, a 3 1/4" hole saw and went to work.

First, I used a piece of cardboard to design the basic pattern.
Second, I traced the cardboard onto the steel and cut out the pattern using tin snips. I used hole saw to cut hole.
Third, I fine tuned the shape with a bench grinder.
Here is what I got:


Next, I installed weatherstripping on the very sharp edges.
I bolted the air filter assembly and shield to the MAF sensor :


Final product:


Testing tomorrow.

 

Way cool man... I made something similar on my 4th Gen Maxima. Kinda isolates the noise too...High five on the black Headlights too..way too scared to try it myself.

If anyone has a white Maxima, and has the headlights painted white, please send me a link sometime...

As allways!!!! TOP NOTCH.

Black Paint, red weather stripping.

Life is perfect.

nice work

i'm always skeptical about those 'cold air' boxes. i'd imagine heat can still penetrate around it somehow, the air within the box and engine area won't be that big of a difference.

 

They work, more cold air will come from underneath. Plus with a good coat of ceramic spray, your golden.

nice! but will it work?

 

nice job man

 

Saw this on altimas.net a while back, figured it might be worth doing. Good job.

 

so deus you test it?

 

Be nice to compare IAT's.

 

Where are the results?

 

Drove it today. Pulls hard and the intake sound is a bit quieter from the inside of the car.

 

I forgot to mention that a few weeks ago, I cut out the right side of the OEM air scoop which sits over the radiator. For some reason Nissan blocked the right side. I unblocked it so it allows more air into the air filter area.

AFTER

 

Wow. Nice work. Good to see people doing some real modding.

 

Real modding includes #'s.

 

Hmm. Touché.

 

I dont need no stinkin #s. If u wanna see how it runs, pull next to me at a stoplight and we'll see who gets away first, lol!!!

 

I feel your times at lone pine were proof enough.

 

Unfortunately, I did not have this cold air box installed at Lone Pine. I am also looking for an air filter that has more of an open element in the front and is not blocked off like my Stillen filter. That way, the air from the opened up scoop is flowing directly into the filter.

 

Amsoil EaAU is your friend.

 

After a few weeks with the air box, I'm pleased with it. I noticed today in our 100+ degree weather that the air box shield it hot to the touch, but the air filter assembly is nice and cool.

 

always a spectacular job as usual deus! Now i wanna swap my Fujita for that short ram + box

 

Well there is certainly no risk of water inhalation!!!

 

Nice, I might have to see this mod in person!

 

haha man i was beyond worried this whole winter.. we had storm after storm towards the end of it and huge puddles of water when everything was melting in the northeast D:

 

ahhh god blesss california hahah we had like 7 days here in so cal that rained... hahah we all might burn down but i dont have to wrry about my fujita eating air

anyway... nice work dues hope to meet you soon and check this out in person

 

I actually have to do a litle trimming. By the way, if anyone is interested in my template, I can photocopy it and send it. I works on the Stillen short ram intake. Whats interesting is that it is quieter on the inside of the car, but has the same lovely noise on the outside.

 

deus...great job on the air box...i noticed that your foam insulation piece that surrounds the stock air scoop is disintegrating, as is mine...do you think this piece should be replaced or just leave as is...thanks for your imput...

 

The rubber insulation is designed to create a 'seal' against the hood so as to funnel the maximum amount of air coming through the grill into the scoops. It may be worth replacing it with weather stripping (from Home Depot) to 'rejuvenate' the seal again.

Besides, it looks better that way!

 

I do think it is worth replacing. Im just not sure what stuff to use. I am certainly open to suggestions.

 

I'm thinking self-adhesive rubberized flexible weather stripping like they use to seal gaps in doors and such. I'll go wander Home Depot and get back to you.

 

Deus...I'd be interested in the template...let me know where to send my address. I asked this question a while back in the forum to see if there was such a box to separate the intake from the engine. On past vehicles I've owned, i.e., VW Passats/Jetta VR6's, I always had an intake and it came with the separater.

Thanks for doing this mod! This is a great one. Also..cutting out the factor air intake looks like it works well too! I'll have to look into that one as well as replacing the cheap foam seal around it. Thanks! Let me know on the template!

Did you come from a b5 or b5.5?

 

I had originally, a 2001.5 VW Passat when they first came out...got a great deal off the show room floor. It was weird...cause it was not much on the road...so I always got the looks and the honks. Then I traded it in for a 2002 VW Passat...

Jimbo

 

hmm interesting.... I'm shopping for an 07 to replace my 2001.5 GLX! What are your thoughts after owning a b5.5 (and how long did you own it?)

 

................excellent!!!

 

thanks for the responses regarding the foam insulation around air intake...i will look around at home depot or our local valu home stores...if i find something i will post info...thanks again...

 

I loved my Passat(s). Only traded in the 2001.5 GLX for a 2002 cause I was sick of having a black car, black interior...lots of cleaning. Then I had my 2002 till December of 2004. A Soldier ran a stop sign and took off the front end of the car (from the front wheels forward). Anyhow, my airbags didn't deploy...I was very concerned about that. VW did an investigation on the car and determined that they hit me at just the right angle to not set off the airbags. Either case, I was not comfortable with getting another VW Passat so I went with a Nissan Maxima after a lot of research.

Right now, I'm not too hip on the new body style of the Passat. It was unique before...now it's just there. But it has more HP than previous versions though...

You think there would be any advantage to having a similar box made for the Fujita? You could almost make it run parallel to the ground to seal off the end of the Fujita tube.

 

Here are three more pics of the cold air box:
