Hacked Air Box (OSCAI) How-To & Results
Okay....got bored and decided to hack the ole' air box.
Not bad for a 10 minute project.
Complete write up on my site.
h4x0r air box
hope this helps some of you new guys out, or maybe entices some of the older guys who haven't done it yet to do so.
Took it out afterwards and had a deeper, throatier growl in 1, 2, & 3 gear. 4 & 5 gear my friend said he could hear as i went down the road, although i could not. (I didn't hear it because my windows were down. If the windows are up, you will hear it in 4 & 5 gear as well) That was while going towards WOT. Going normal driving speeds, it was just as if i had not hacked the air box.
As far as gained HP, small amounts of gained HP are generally not noticed. However, one thing i did notice was a willingness to head towards the redline a little faster. Nothing huge now, but it all adds up eventually.....right?
On thing that i will try is to see if there is noticable difference in running with the cold air scoop, and with out the cold air scoop. There should be some slight yet un-noticable gains in running the hacked air box with the cold air scoop. The reason for this being is as follows.
Cold Air Intake (CAI) generally have good lower RPM HP response.
Hybrid Air Intake (HAI) generally have good mid RPM HP response
Middle East Variable Intake (MEVI) generally have good high RPM HP response
That means that the hacked air box is a Semi-Hybrid Air Intake which should give you a fair low and mid RPM HP response.
If you were to take of the cold air scoop, you would essentially be running a Hybrid Air Intake.

Did'nt see a reason to hack more of the box away, althought......
You could just cut off the upper lip of the lower air box, the part with the clips. Cut that off, rotate the upper air box so that it fits upside down on the MAF, and then reinstall the air filter and the cut off lower air box's upper lip. Then you have a pannel filter set up to breath all it wants, and the filter is easy to get to and replace without having to dismantle your whole intake setup.......
?? I would like to see some picks if someone would do this....

Now I was thinking about doing this but. . . how loud is the growl and how deep. . . i had a K&N cone filter with just the adapter and it was bugging me because it was too loud for me and it annoyed me. . . is it as loud as that??? I don't want to cut my box and then not like it.

I might be willing to try and do that. I've been looking to pick up a spare box from someone. I've been checking the classified forum but havent gotten anything yet. Anyone want to sell me theres?
I'm thinking about hacking my box like you did. But i have some questions? I dont have anything else done to my car. Engine wise. Is this beneficial to me in any way? Or would i just be making it louder without the help of a CAI, or HYbrid or some other intake? Thanks, and hopefully i'll find a spare air box soon that i can practice on and report back to you guys.

Since you are only allowing a minimal amount of noise to come out unbuffered.......unlike a cone filter which allows any and all noise to permeate thru the engine bay.
as for mrglynis............... if you can find it, go for it......it would just be an easy way to create a HAI without having to buy or create much.

Also keep the resonator. The midpipe desinged intakes (some people call them hybrids) have really poor low end and midrange power, but good high end (after 4900rpm.)
I really enjoyed my hacked air box, the sound was great.

1. check ur codes http://forums.maxima.org/showthread.php?t=104931 ; you most likly forgot to reconnect your air temp sensor or your maf
2. yes, thas why you can use a k&n and reuse it over and over

Air flow from the bottom of the air box up through the filter and into the throttle body. So as long as you only cut the bottom half of the air box your car will always get filtered air.
