Homegrown SRI
So Booyah's GODCAI
got me all excited about starting a project that I'd been thinking about for a while: a home made short ram. Sure, you're thinking "why not go for the CAI while you're at it?" And you'd be right if it wasn't so wet up here. I'm honestly afraid that I'll get a soaked filter and an engine full of dirty coffee-laden H2O. 
The whole setup from start to finish was $25
including the $20 filter and the duct tape that I had to buy because I wanted it in yellow (I don't know why either, don't ask
).
So, here's your shopping list:
1) go to homestore and buy a "3X4X4" rectangle to cylinder adapter in the plumbing department. It's with the rest of the irrigation stuff.
2: get some gasket material (the cork 1/8th inch stuff works well) and a small tube of automotive silicone.
3: duct tape! (the handyman's secret weapon) Use this to make the body of the cylinder the same OD as the lip (there's about an 1/8th inch difference). It doesn't take much, but you'll have to tear about 1/4 of the width off to keep from building up the lip.
4: the biggest *******ed cone filter you can find. Mine's a FRAM CA8039. They're designed for something like Ford F-series trucks. K&N makes one too, but I figured I'd wait to see if this even works. And the fram is even cheaper than the APC or Weapon R cone filters that they had at my parts store. Score!
And to put it together:
*Take the old box filter assembly off. Prety simple- be careful, don't break anything that you might change your mind about later. I also took off the mounting plate- 3 extra bolts and I had to break the little clip that held that wire bundle to the plate.
*Take the wires off of the MAS (if you haven't already) and take the MAS off of that big hose. This is a pricey part- don't let the neighbor kids play with it.
*Make gaskets. Be careful to make them so the gasket materila won't flake off and get sucked into your engine. That's bad
Also, this is a pain in the ***. Take your time. Some of you may just take silicone and make a big fat bead and pop the adapter on that. That's ok- I guess
. I actually used some 1/4" vacuum hose to make the first gasket that fit onto the adapter and superglude it into place. Be creative.
*Drill little (1/16th inch) holes in the corners of the adapter, near the side that will be abutted to the MAS.
*Thread wire through these new holes, through the bolt holes on the MAS and make like twist ties. This does a pretty good job of holding things together. You may want to silicone. Ultimately I did.
*(if necessary) Wait appropriate amount of time for sealants to dry
*Duct tape! the neck of the adapter, don't build up the lip.
*Fit filter.
*Pat self on back. smile big
*Take filter off again to facilitate reassembly of your new SRI.
Make sure everythings tight and force the filter back on. It'll go between the battery and the engine.
*Close hood and VROOM!!
* (optional) take pics and post your own SRI story. Be sure to update your registry:

* (optional) Used the money you saved on a store bought SRI and buy
for me and Booyah, that big ol'

Good luck!! and enjoy

Side view
edit Mar 22: This is a new side view to reflect that I reinstalled the stock air dam and the filter is now supported by a bracket (see below)

Serious improvement over stock. Especially for $25. Sound is bad *** (very deep and throaty) lots of pickup as soon as you get above 2700 and even below there's a noticeable difference. Maybe if there's a dyno day in Portland I'll be able to come down as we can see how much gain there is with GODDESS-SRI and the test pipe
Oh my God. Look at what you've started Stew...
Good job on the intake though! Only question: is the filter itself attached to anything other than the modified mas, or is it just hanging freely?

way to think out of the box...but i have to agree with ghost...if the filter isnt attached to anything you might want to so there is no added tention to your MAS and other important parts.whit the extra weight even just daily driveing may pull on it and cause stress

In a few weeks I'd planned on making a sheetmetal heatshield (coated with ceramic impregnated paint). I also need to replace the stock hose from the MAS to the throttle body- that filter's huge and it'll need more room to get a shield around it. I'm also trying to come up with a way to vent air from the driver's corner "vent" to the engine bay for some colder air.
Of course, she might have to be painted AGAIN! (f-ing rockchips) and that would set my timetable way back.

update: I moved the filter back behind the battery to get it away from the engine a little more. Also I made the bracket to hold the filter in place tonight out of 1/4" round stock that I had laying around the smithy. Good idea ghost
It's being painted and will be installed tomorrow PM. Also, I'm reinstalling the front air dam to try and direct some outside colder air into the filter.

Here are some pics of the bracket that I'm using to hold the filter in place. It's snug (the filter can't really move) and the 1/4" steel that I've used is more than strong enough. I bought a new bolt to accomodate the thickness of the material. I used my tempering oven to bake the layers of primer and paint onto the part.
