Note to all:
I did end up purchasing enough complete parts(kits) to install this on about 10 cars. Might work out a deal with a distributor to maybe mass produce a kit. </end side note>


Custom Air Intake System
Modification Update



Overview of tools used:
-Philips Screw Driver
-Flat Screw Driver
-Socket Set
-Two Hands
-2-3 Zip Ties
-Patience


Overview of parts needed:
-AEM DryFlow Synthtetic Cone Air Filter [3in/9in pn: 21-2039dk]
-MAF -> Cone Air Filter Adapter
-4 bolts, 4 nuts, 4 washers.
-2-3 Zip Ties


Why:
-Increase air flow, reduce air restriction.
-Car sounds like a race car ;-)
-IMHO it's an upgrade.

about:
The AEM DryFlow filter is the latest update for new filters. It does NOT use oil. It is a synthetic filter. It is reusable and will not ever have to be thrown away. After a certain amount of miles used, requires removal, soaked, cleaning solution, dried, re-attached. To find out more information about AEM DryFlow filters see: here



Step 1:

Examine your current air box situation.




Step 2:

Quick Tip:
-Remove top of air box
-Remove ISV & attached hoses
-Remove MAF plug sensor
-Remove front air intake housing (piece right behind the passenger side headlight)
-Remove bottom of air box
-Remove stock air hose, (the part/hose coming from the throttle body, simple clamp unscrew).

Remove ALL stock air box parts. Be careful. Majority of the parts you are touching are old hard plastic. Don't break anything. Start out by removing the top of the air box, as if you were going to replace the stock air filter, 4 metal clips hold the top on. The delightful owner of my car before me decided to put in a K&N filter panel, IMHO bad idea. Proceed after you get the top panel off and remove the filter. Be sure to unscrew the ISV controller from the side of the stock air intake system before removng it (I temporarily removed the ISV all together). From there you can remove the stock intake hose coming from the front of the car by the passenger side headlight. It has two tabs that you are going to want to release and then it just slides straight up and out. Once all that has been removed proceed to remove the lower bolt holding the bottom of the air box in place. The correct socket (I think it was 11mm, majority of the screws on this car are 11mm), and a long extension should do the trick just fine. Once everything is out it should look like this:




Step 2a:

Picture of ALL the stock pieces removed. The very top piece you will replace at the end of the install.




Step 3:

Either purchase, find, aquire, whatever you have to do to get a 3 inch MAF -> cone air filter adapter.




Step 3a:

You will also need a 3" cone air filter up to 9 inches long.




Step 4:

Mount the adapter to the MAF.




Step 5:

Mount the cone air filter to the adapter & MAF.




Step 6:

Reinstall the stock hosing, MAF, adapter, and new cone.





Step 7:

Zip tie and/or leave be the ISV back into place.




Step 7a:

Be sure to re-plug in the MAF sensor.




Step 8:

Make sure your car turns on ;-) Enjoy your new air intake system.


Closing Notes:

In closing, this actually worked out and installed much better than I originally had planned. The longer 9 inch cone air filter tucks and extends under the front passenger headlight getting air from the front air dam.

Going to fabricate a heat shield of some sort and maybe an air duct pushing air up further.
