This modification uses Vinyl air ducting to collect air from the grill area and feed it to the intake. Since doing the modification, I have noticed a decent increase in low end torque(below 4K RPM). Not very noticeable on the high end. The best thing about this modification is that I can run my A/C now without feeling bogged down. I barely even notice that A/C compressor is running now.
Note: You will not find vinyl air ducting with Dryer hoses anymore. They are seen as a fire hazard. I looked at Walmart and Lowes and could not find any. I finally found mine at Ace Hardware.
Another note: I combined this modification with a grill block. If you see clear tape on my grill, that is what it is from. I don't recommend using the clear tape to do a grill block like I did. It holds moisture.
What you'll need:
Vinyl air ducting(Got mine at Ace Hardware)
Mesh for front grill
Step 1: Cut out one of the sides of the ducting for as long as you want your air vent. I went about a foot and a half. Leave the wires to help wire it to the mesh. Duct Tape it up to increase strength and make it look better. I cut off about a 2in piece and duct taped it to the end to round it out. You can see it in the next step.
2. Wire it to the mesh.
3. Cut your air box
4. Drill Holes in the bumper and zip tie the mesh to it. I took my bumper off to do this to cut the hole in the next step.
5. Cut a hole in the metal under your air filter big enough to run the air ducting through. Throw some duct tape around the hole to keep it from cutting the ducting.
6. Attach the hose to the air box with more duct tape.

Sounds like your end result was a good supply of outside/ambient air [instead of hot under hood air].
Even with a preferred large intake funnel [which you don't have] , it would take at least 50 MPH to get any ram air effect.
let the car idle and put your hand over the inlet, and see how hard it's sucking the air in. i'd be curious how well it would do when a street gets flooded.

nicro cowl vent.jpgRamair Scoop 003.jpgRamair Scoop 004.jpgI did it back in ' 97 , changed it a few times but always maintained that the system must be sealed to be able to pressurize . There can be no hoses , holes or anything connected to the induction tube . So from the inlet to the TB , nothing from outside is connected . If you can cover the inlet an the engine dies it's good to go , if it still runs it's not going to pressurize . The Red scoop is a Cowl vent used on boats it's pretty big . The Black one is my latest venture , there again it's pretty big . I've had probably 6-8 different scoops that I've tried , the Red one(now black)I seems to always go back to as moving the most air . The Black one is larger and will move a lot of air , just have to figure how to make it fit . I use a Millibar gauge to check for pressure , a regular vacuum/boost gauge isn't sensitive enough to detect any pressure raise .
Rain heavy or light has no affect , same with snow . If you run into deep water to you know is going to get into the inlet , go around or wait . I got rained out of the house once when the street flooded , waited about a 1/2 hr till it went down . Same with snow if it's deep or drifts avoid . If you have to go a certain way , take the induction tube of the filter can then go for it , car is light so it floats pretty easy . I'll try to get the webshots to load , use to work but lately it won't load . Copy an Paste and it'll go through . From there you can check out the other albums .

^Very nice, the black one looks about perfect for an 03 with no factory fogs
I had fun adding ram air to mine. Dive you have a pic of the final project? Like others have said, I have to avoid deep water.
Mine is below...
This is the only view you should see when on the road with my S/R!
I'd hit it really hard too!
