Default Stock Airbox Problem

Just an FYI I was looking at my Bonnie today contemplating putting in a CAI when I noticed that where the stock airbox attaches to the corner behind the headlight on my 00 SSEi a foam piece connects the hole in the box to the frame. In my case the foam had come partially off and most of it was sitting right in the hole where the air is drawn in. I removed the entire foam piece (which was sticky glued to the airbox) and noticed a considerable inprovement in my acceleration due to the better airflow.

Just thought those who havent put in a CAI yet might want to check to see if they are having the same airflow restriction.

Todd, can you post a pic? I'm lost, but also unfamiliar with the 00-up airboxes.

Yes Rogue you are right. The airbox setup on the 00-03 ('04?) Bonnevilles is not the greatest. I took my own time to construct a completely personalized air induction on mine. I believe in the more air the better and if I change something I don't want it to be a restriction in the future so I tend to go overkill with some things. I bought a 15"X 6" K&N cone. Mount it directly on the Throttle body. Take a razor blade and cut an X shape to stick in the IAT sensor. Put some good epoxy around it and thats done. Then if you really look at the "wasted" space there is plenty. On the SSEI, where the trans mount is, if you look right next to it is the TC solenoid. Look directly toward the driver tire, and there is a huge opening directly under the factory airbox and right in front of the Driver wheel well. Also, toward the rear of the engine compartment is a huge opening above the driver side inner tie rod. If your good(have too much time on your hands) with plexy glass and epoxy, you can create an airbox at least 10 cubic feet. My airbox covers this entire area, blocks out exhaust heat, and by no means is it at all restrictive. Its not the prettiest thing in the world, but it was my home made piece. So, my "airbox" starts in the front corner behind the headlight, comes all the way across to the brake booster, just below the master, down with an opening on the bottom both at that tie rod area and in the area in front of the wheel well.

Sounds like a lot of work. Im thinking of doing something similar to SilverBullets setup. Do you have any pics of yours?

Although I have not personally experienced this problem, I can definately see it being a problem. Most of the owners on here have gutted airboxes, so they don't have to worry about it, but for anyone that doesn't have a gutted airbox or didn't remove that part when they gutted it on a 2000 or newer, DEFINATELY check and see if this is happening. The worst thing that could happen is you could find out it isn't a problem...on the other hand the best thing that could happen is you could gain a horsepower or two.
