thats how u make it... I hear it sounds really good...if that helps u at all...its a simple mod.

 

pleas read the stickies before posting questions thank you

 

cut holes, or take bottom out like i did and find a way to keep the filter on there. sounds great. cheap to nothing price!

 

It sounds reeeeeeeeeeeeal niiiiiiiiiiiiiice.

 

you can hear it only when you drive... when you are parked P and rev the engine it doesn't make any sound ... but it does sound real good when you rev your engine while driving ! heh

 

...and of course, lets not forget the horsepower achievement guys. After all, one gains a stunning .02938 hp

 

yeah it sounds real good when your driving almost like a v8

 

It definalty does make noise when you are parked and rev the engine, that was the first thing I did after I hacked mine.

Why wouldnt it?

 

Yes, it does make a small ROAR in park. But, when you are driving - it's a different story!

 

soo all i do is cut holes in the stock airbox... under where the airfilter is in?

 

yes - defintely UNDER the filter. you will be screwed otherwise

 

haha if you put holes above the filter.. than it defeats the purpose of the filter! LOL

 

ur getting sound...thats about it...u do relize that right. HP boosting isnt really a big option on this.

 

Get a 3" hole saw and drill out 2 holes on the SIDE of the BOTTOM part of the air box. You could even cut the whole bottom of the air box off. Once you take the air box out of the engine bay you will understand where to drill the holes.

Ok let me go take some pictures...Might be a little while.

 

Theres pics in the faqs

All you are doing is putting holes in the bottom of your airbox, its pretty self explanitory

 

I didn't take my battery out. It's just above freezing outside. You can see the holes good enough with the battery in there.

Picture #1: Taken from the driver's side of the car, up close to the hole. You can see the big hole in the front of the airbox. That hole is underneather the air filter. If you take apart your airbox/intake, this is easy to understand. This hole was made with a 3" hole saw. I drilled 2, 3" diameter holes and then one more to connect both holes. That made one big hole.



Picture #2: Taken from the driver's side of the car further away from the air box. Same as the first picture. Holes are cut directly behind the battery.



Picture #3: Taken from the driver's side of the car. Notice the 1.5" diameter hole in the fender side of the airbox. This hole is also underneath the air filter.



Hope that helped...

 

I have two audio clips of the Hacked Air Box Mod recorded from inside the car and above the air box. I can send them to anyone on AIM. I don't know where to post them. Both audio clips are taken while the car is in Park.

 

damn so its just a hole
why does it make such a big difference
i want to do this though

 

i wouldnt gut the whole airbox - then youre just suckin hot air of the engine block, which is obviously not beneficial or good. by drilling holes youre gonna get some hot air but i would try to minimize that by cutting on sides away from the block.

 

id like to hear it

 

so is blackmaxima's cut properly?

 

Yea, I know what you mean. But, the ROAR is phat.

I guess you can cut it anyway you want. I saw in another post someone cut the whole bottom part of the air box off. That's basically the same as a Short-Ram intake but without a Cone filter. I don't see how mine is any worse than no air box at all.

 

o most definitely - and i only cut that one side and it still sounds awesome

 

box pics the way this guy did it he has a whole bunch of pipe he made going everywhere...midpipe and whatever. do you need to do this? or is this just a way to get cold air.
if u just cut a hole in your box, will you hear it or do you have to do all this ****...

 

so this doesnt do any damage does it?
just the one hole

 

I just cut the holes and heard the noise.
