I have been planning on doing this for a few weeks but I must give credit to urban_assault_XB for being the first to post this idea and giving me the motivation to do it.

If you dont have the extra money to spend on a intake or cant see spending all that dough for such a little gain than this might be the ticket for you.

I chose a $ 25 Ractrive air cleaner with a 3 inch inlet.

Alright open the air box and remove the stock air cleaner, then loosen the clamp at the throttle body and remove the hose to give you some room. Take the air inlet hose that goes into the bottom of the air box off. Cut it at the point where it is ribbed. See picture.

Simple enough now attach the air cleaner

Now reinstall the lower hose with air cleaner to the air box

Put the intake hose back on the throttle body and close up the air box. Your Done

I think for $25 bucks and 20 minutes worth of time you cant go wrong.

After driving the car, it sounds alot better it has a nice tone and I do notice a slight diffrence in throttle response and power in the 3000 to 6000 rpm range.

Again if you dont have the loot and have 20 minutes what have you got to lose.

I will bring my Xb to my friends shop and dyno it to see if there is any diffrence. Of course you will all be the first to know.

Very nice DIY and pictures are always an added bonus....thanks.

Wow, very impressive SUPASCIONXB!

So, the stock airbox is still part of the mix in this mod, pretty original thinking :wink: !

Thanks! Looks nice and clean, too...

Nice! Good job on the DIY, man! Now somebody needs to Dyno this thing. :wink:

wish ya could extend it a little and make it go under the headlight... that would be sweet...


great job tho..

You could get some ducting...but that might slow down airflow (since it's ribbed)

Nice job looks great, just like mine email me at urbanassault_16@hotmail.com when you get it dyno'd. Like you said I felt the car pulls a little stronger in the upper rpm range.

here a pic of mine

I love it :lol:

That's perfect... You still have the stock airbox in there, with no paper filter inside!

I'm gonna try that out...

Good lookin' out.

-THE DON

Thanks for the pics. . . where did you get that filter? I thought Reactive was an APC filter. . . guess not.

nice job man, thats EXACTALLY what i just did, although I want to elminate the stock air box from the equation, but i dont know where to put the maf sensor. throttle response does seem a little better and it definatly sounds nicer, which really was the only effect i was looking for

I just completed mine... It actually sounds exactly the same. I'm not sure if it's any hp improvement either. We'll see when I get it on the freeway!

But hey, I really just wanted to get rid of the stock paper filter, and this mod is actually cheaper than buying a drop-in K&N filter, and probably works better!

Props to SUPASCIONXB for a tight azz mod.

did you remove your stock filter?

SUPRASCIONXB. . . I first I was a doubter, but now I see the light!

You are the man!!!!!

YOu think the xB was hard? The xA was a PAIN IN THE @SSSSSS!!!!! Talk about no room under there. The battery wouldn't fit. . . but after about half an hour of fiddling, it somehow just fell in!

I will post pics tomorrow! This thing sounds MEAN!! A little on the loud side, but if I go easy on the left pedal, it's ok. It's not like these cars were Lexus quiet to begin with. I think power decreased a little in the 500-1000RPM range, but when you get past 2500, if seems as if there was a small bump in power. But the sound is absolutely wonderful. It no longer sounds like a whiney cow, but like an angry monster! If you are ever in CA, I will buy you a 6 pack!

whats the numbers on the dyno??
any difference?

did you remove your stock filter?

Duh :roll: j/k Yes I did.

Mine doesn't really sound louder though. Which is good, I didn't want loud. And I also had to move my battery just slightly. But I did buy a bigger filter.

It does kinda growl at high rpms though... I definitely think it's a better and cheaper upgrade than a drop-in or TRD air filter!

I'm surprised you aren't seeing as big of a difference as I am. . . must be the filter type. Have you tried flooring it?

only prob is that without the stock filter there is an air gap at the air box clam shell soo unfiltered air can enter. what ya gotta do it tear up a stock filter and just use the outer sealing ring to keep all the dirty air out :wink:

better hope u dont get ne water in that guy!!

better hope u dont get ne water in that guy!!

The filter does not look like it rides any lower then the stock one. So getting water into it, would be about as hard as getting water into a short ram.

It looks great but from previous experience you are not really going to get that much more air in there. I doubt the dyno will show anything because the car is not moving. A drop in filter lets the car stay alot cleaner. You will be sucking all the dirt from the motor towards the filter area...

Its going to be hard to dyno since the car doesnt move on the rollers.........What u see is what u get

Yeah. . . I found out about the leak today. . . that's why it was so loud.

Also, the seal around the filter is not grade A, and can be prone to leaks. . . and since it is aft of the filter, this can lead to problems.

I'm gonna get an Injen intake, but this will have to do for now:

IMPORTANT STEPS:
1. Seal the stock box, either by cutting the OEM filter(bad, because shards may enter the engine), or by sealing with tape (I used both HVAC tape and duct tape, and used MANY layers)
2. Melt any rough edges on the cut, on the OEM pipe, to ensure that no loose plastic shards enter the engine. . . a lighter will do. I also used another few layers of HVAC and duct tapes to cover the edge.
3. Seal the filter, by using layers of tape(again I used the same tapes)

A) the xB may see some slight power loss, as the factory airbox already draws from a cool air source. I can't imagine any significant/worthwhile gains, drawing in underhood heat/air
B) the xA's OEM intake already draws air from the same location as the poorman intake, so there won't be a significant increase. Any gains will be a result of the larger filter and the less restrictive material.

Secondly, when mounting on an xA, the battery will have to be removed. You will probably have to remove your battery tray ( I did, but this may not be necessary). You will also need to use an air filter that has a slightly tapered head. . . a cone shape.

djct_watt, please repost your pic.
:idea:

pics are bein a holes. . . PM sent

pretty nifty.........thats just what i was looking to do, wasn't sure what to do with the mf though, i thought about using a reg, generic intake from the auto parts store ($50 bucks) and drilling a hole for the sensor and using self tapping bolts/screws.........any suggestions about this method? anyways, i have an upgraded muffler, and it sounds good, but im looking for a bit deeper tone, i think this might help.....ill post pics after i do it...

I suggest you shred the filter and use it as a seal, and make sure ever clamp is double, triple, and quadruple sealed. Secondly, I HIGHLY recommend that you get some PVC pipe or flexible tubing, and connect the ends inside the empty OEM filter box, so that you get a deeper tuned (less resonator effect from the box) and a free-er flow.

hmm....lowes and homedepot are closed.......wonder if walmart will have these parts :) i can assemble it at a 24hr car wash! away from the rain and in the light.......also....so basically you attached a filter where the stock intake gets its air from, and removed the stock filter? (with some minor adjustments to seal it)

Graet job and the pictures are highly appreciated! Like I said before nice and clean looking and after suggestins from the above should make for a nice improvement any way you look at it...

or you can get real creative, the other poormans intake I spoke about

Looks like a little like the Blitz intake. I rather have an intake that looks like this pic. Its nice to have the Injen short ram intake, but when its time to change filters, its a pain in the a** to do. Take out the battery then the whole intake just to change the filter? Nice job! If this design runs like the Injen intake, then definitely, I am game for this!!!!!

is that a cut up stock airbox?

could i simply take the piece of tube that the MAF is on, and attach a generic intake on either side of it......so that it will only cost me like 50 bucks for a "real looking" intake?

eh... think about it man! If you attach filter to both ends of the MAF sensor, ur throttle body will have no tubes connecting to it therefor defeating the purpose of the whole intake system! might as well remove the whole freaking intake and run without tubes. :lol:
