Tools Needed:
[size=11pt]

  • [size=11pt]A thin blade slotted head screwdriver (for releasing clips on the electrical plugs)

  • [size=11pt]A Phillips head screwdriver or drill driver
    [size=11pt]Various hole saws (recommended 7/8", 1-1/4", 1-1/2")
    [size=11pt]Alternative to hole saws: Drill bits and a  saw suitable for plastic, or a Dremel tool (credit goes to the Saint for reminding me of this option.)
    [size=11pt]Tin snips
    [size=11pt]A vise, helps but is not necessary
    [size=11pt]Round and/or half-round single cut smoothing file
    [size=11pt]100 grit sandpaper
    [size=11pt]A clean rag and/or plastic baggie and rubber band


[size=11pt]Time: 30 mins - 1 hr.

[size=11pt]Admittedly, this procedure is a stop-gap measure and will probably (hey!  Who knows, right?) not produce the kind of results a properly designed/ engineered CAI/SRI would, but is none-the-less is a fun little no-cost mod one can do in about an hour should you decide;
1. you don't want a CAI, or SRI
2. you do want a CAI/SRI but just can't wait for it to be delivered and are bored waiting for it.
3. it's a low priority as you have other things to spend the money on first (my excuse.)
4. you think $150-$300 is a lot of $$$ for a piece of polished tubing and universal air filter (my main excuse.)

This mod should produce an increase in power, based solely on my seat-of-the-pants ("Butt") dyno, and will certainly sound  a hell of a lot cooler than the stock, closed airbox. Working together  w/the exhaust I installed I notice a big difference in everyday driving, especially in mid to upper range power.

Also, as is obvious from the pictures, I have chosen to use the K&N replacement panel filter (around $40) which I had already installed before doing this mod.  Using the stock filter should give you almost  the same results, though the K&N does breath a bit easier.
   
It should also be noted that the pictures used for these instructions  were taken after the fact.  As is my usual style, I wasn't thinking about pictures (or a write up) when I originally did this.


Remove the airbox cover.
To do this remove the three "Fisher-Price" screws and clips holding the little plastic triangle thingy (#1) connecting the battery box snorkel to the front apron. (Mine is permanently removed, but is represented by the outline marked #1 in the picture.)  Remove the battery box  cover (#2) and finally the snorkel (#3.)


Next, disconnect the PCV hose (#3) by squeezing in the tabs on the blue collar to release and pull the hose off.  


Disconnect the sensors (#1 & #2.) Using your flat bladed screwdriver helps to release and hold the clips.


Using the Phillips head screwdriver, unscrew the clamp (#4) @ the throttle body. 
Release the four clips (#6) holding the top of the airbox to the bottom.   
Release the small coolant recovery hose from the clip (#7) on the lower left side of the upper airbox, the throttle body hose (#4)  and take out the upper airbox cover.   
Gently push the rag into the exposed throttle body opening, and/or cover w/a plastic baggie to keep out dirt, dust and other contaminates.



Remove the stock air filter from the airbox bottom.


Remove the bottom part of the airbox.
[size=11pt]Pull off the rubber pull ring (#5) that holds the front of the box down.
Now that everything is disconnected, grab the bottom part with both hands and pull straight up.  It will pop out of the two rubber bushings near the back of the box that hold it to the frame and away from the inlet duct.






Doing the MOD.
If you have a vise, now's the time to use it.   
I was trying to drill my holes w/o compromising the integrity of the support structure of the box so three 7/8" holes on the far right (fender) side in between the reinforcements are about all you can do, unless you wanted to elongate them vertically.
Next come the two 1-1/2" holes on the right near the inlet duct. To maintain integrity, I decided not to connect these.




Originally, I drilled four 1-1/4" holes in the front then decided why not connect them and turn them into a long slot instead, so I used my trusty tin snips to cut out the excess. 
If you're not lucky enough to have a decent set of hole saws on hand you might drill some pilot/access holes (3/8-1/2") and use your various blades here instead of the snips.




Finishing it off.
NOW, get out your file(s) and sandpaper, and proceed to chamfer  and smooth all the edges removing any burrs that may have been left from the previous steps.  It really doesn't take that long since this soft plastic is pretty easy to work with.
Make sure all the shavings and dust are cleaned out before you reinstall the box.  (Duh!)
I've kept all the holes to the front, or fender side of the box to give it a chance to draw in as much cold air from outside as possible and to help avoid drawing in all the hot air around the engine itself.  It may be moot, I can't be sure. I will surely never know definitively.

Now that your bottom box look like Swiss Cheese ( :lol: ), you've accomplished the mission and can re-install everything in reverse order. Then you can enjoy the extra power and the Whooot-Whooot!  sound when you step on it.

It's working for me! Instead of using the default 2,300, use 8,600+/-.
As I'd said in the text, the "Butt dyno" says YES!!! Sound and smoothness were improved, but when the Vibrant came along.... look out, Baby!! To me it's a combination thing w/the exhaust.

Re: How To: The Poor Man's SRI

Hey rich, Have you thought about getting an adapter say from autozone and sticking a cone filter to the stock tubing? I saw these adapters this past weekend while trying to fix my buddies car and thought they might work. I would need to look at the tubing and see if there would be enough room. I know it wont carry the name of a quality made SRI but hell. It should be at least pretty close to the gain you would get from a "real" SRI. Whatcha think?

Re: How To: The Poor Man's SRI

It could work, but by the time you do all that you may as well just buy one of those cheap CAI's from someone on eBay. Dontcha' think?
The idea behind this quick little mod is that if you haven't the money, the time to do research or simply haven't found what you think you're looking for, you can still do this in an hour and add some "bling!" nowotImeen?
You still haven't told me if you're going to try this and see if it makes a noticable difference w/your exhaust.
See, I did this first, before the exhaust so it's hard for me to know which made the most difference.

Re: How To: The Poor Man's SRI

hehe, gotta love the cheapie mods. I had done similar things to the saturn. And your right, if nothing else it changes the sound and many times that makes it worth it. Especially if you're just waiting for a part to get there. My only qualm with this particular mod is that theres really no way to return it to stock without spending more money. Just hope your intake dosn't ever cause problems because if they see those holes in the airbox they aren't going to fix it.

HAHA ok. Well I tell you what. I am going to go look at the prices for getting that adapter and cone filter. The adapter if I remember correctlly is 3-4 bucks. I love the idea, cause it doesn't cost any money but getting it back to stock or having the stealerships having one more up on me scares me a bit. lol. We'll see I still have 2 more days till the weekend so I got a little time to think on it.

...and you forgot to mention, any performance increase is FREE POWER!!! How often can you say that about a modern car?
Of course you're right about the warranty issue, but I have an '04 and am nearing the end of warranty anyway. I figured I could always aluminum tape up the holes if it didn't work out as expected. Not pretty but it would work. Then later get an SRI.
So far (knock on wood,) I haven't experienced any warranty issues even near that part of the car.

Re: How To: The Poor Man's SRI

Well after an extensive search at Autozones website I have found that the couplers are 6.99. plus a fliter I think will still be under an Ebay one. Plus I will still have the stocker to put on just in case there are any warrenty issues since I still have 30k left to go. If I do it I'll throw some pics you way Rich....if you want em.

Then how would you start the car? Aren't you forgetting about the MAF sensor, and whatever that other thing is, not to mention the PCV hose?
And you too, Saint. What are you gonna do about those little things?

Well I'm not thinking of putting the filter right on the TB. I want to still use the stock main hose that goes to the stock airbox. The use a coupler at the end of the main house and put a cone filter where the stock airbox was. Will that work or am I still forgetting someting. I'm stuck in work so I can't really go outside to "visualize" what I'm blabbing about haha.

At the risk of sounding like the smartass that I am (sorry, it's nature,) you could look up. The pictures of mine are right there.
Yes, you are forgetting that the MAF and that mysterious "other" sensor are mounted in the top of the box itself. You'd have to figure a way to relocate them in the new adapter, or cut them out and utilize the OEM top. That kinda' defeats the purpose, doesn't it?
Is it worth it? Should it be needed, how much could a used airbox bottom cost?

BTW edrection: I hope you know that I was just kidding.....

Re: How To: The Poor Man's SRI

Good point. No smartass taken haha. Work makes me stupid. After looking at your pictures you are right. All those sensors would have to be moved. I think I would harm less of my warrenty going your route than mine. Maybe I'll give it a try tonight. I'm thinking a drill then expanding the holes with a dremel.

Re: How To: The Poor Man's SRI


Ahhhh.  The ole' dremel trick.  I have one of those, but use it so infrequently I forget I have it!
Not a bad idea.  That should work!
Or, if you're not too far, and don't get outta' work too late, you could come over and we could do it here?
I do have to work early so we eat and go to bed pretty early too. 
What time do you get out?  Where are you?
It is supposed to rain later today starting around 5:00 and I don't have access to a garage. But if you could make it sooner/soon....?

Aaaack!!  You're a thousand miles away, Dude.
I'm on the other side of Manor, way out in the country. [glow=pink,5,800] Why else would I settle for a dial-up internet connection. [/glow]   :p
[size=11pt] (^pink= sarcasm, remember?^)
I was kinda' lookin' forward to helping you w/this and hearing how your LOUD exhaust sounds.  My wife wouldn't be too crazy 'bout that part though.

Re: How To: The Poor Man's SRI

HA actually unless I'm floring it..it sounds like a stock exhaust with just a tiny bit more bite. I really does sound good. There is actually a video on youtube that I posted up that has me reving it. I can try to find it.

EDIT: decided to find it for you... http://youtube.com/watch?v=3cO4ITlhiX0
