A couple days ago, I was cleaning out my air box and dusting the filter when I noticed that the inital tube that connect from the outside into the air box can be disconnected via a small metal lever. Can both sides be disconnected? IF so, I may be able to devise a custom intake pipe to connect into the airbox and at least get a pretty decent increase in airflow to the box. The current pipe is very restrictive, as you have probably seen.
I've been thinking about trying to put a new intake tube with a K&N cone filter on the end. I figured this might fit right in the space where the current airbox is. Is there anyone who has tried this? I know you would probably have to have it custom made, but it would probably work well and add some power.
Anyone have any advice on this?

A poster on other forums spent several hundred dollars trying to do this. First he built a custom carbon fiber air box. It produced no gains or losses on a dyno. Then he tried a modified Pipercross intake. Measured gain was 2 hp. But, wait. A dyno can't measure that accurately. There are too many variables to have any confidence in a number that small. The standard error of the measurement may be larger than the measurement itself.
Unless you have a good grasp of fluid dynamics and the proper research facilities, you are wasting your time and money. Besides, many people believe the stock intake delivers more air than the stock engine can use. Your time and money would be better spent trying to get someone to build you a set of headers. That seems to be a bigger restriction in the engine than the intake.
Actually I'm not so much concerned about increasing the performance. I already have the Kleemann pulley on it. But I like the sound of the supercharger whine and would like to make it louder. I know the airbox and all the piping is silencing the intake sound of the engine. So even if it doesn't add performance, I wonder what is the best intake to use to increase the sound?

Those people are fools that never dynoed there cars. I've consistenly have gotten about a 6hp gain with no air filter at all. The ITG is a start and although I didn't directly dyno the two filters I extrapolate that I got about 2HP. What would likely work is a K&N cone mounted with a 3" plastic pipe about 10" long that drops down 3" so it sits right in front of the existing opening with a heat shield. I found this on K&N's site.
Buell, I noticed on K&N's website that the C230 is one of the cars they are looking for someone to donate for several days so they can design an intake for it. I noticed you are from Southern California, which is where they are I think. I don't know if you or anyone else ever considered doing this. It said they need your car for several days and then you get a free intake when they develop it.
It would be great if someone were willing to do this. If anyone does it, please post and tell us, but otherwise I may just try to make something myself.
I think I am going to take a look at it this weekend and see how much of the current intake piping I can take off. I'm not sure exactly where it goes after the airbox, there are some other plastic covers on the left side of the engine. I may just measure the current pipe that the airbox connects to and get a cone filter to stick on the end of it. I know it would be ideal to put a pipe on it and extend it to meet the inlet from the front of the car, but I think it will be able to find enough air wherever it is at. It will probably suck in as much as it can get.
If anyone else has tried this or any other intake and has any feedback, please let me know.

I found this other filter from Accel that looks interesting. Looks like you can remove the airbox, mount the right end onto the intake where the current airbox attaches and route the other end down to the opening in the grill that the current airbox uses. I think their website is www.koolblue.com.

That is what I did, same concept as the picture above. However, the result is not that good. First I think the cone filter is too small(I exchanged for a larger K&N filter Part# RU-1480 today), second, it is sucking all the HOT air in the engine bay. Even with the air hose attached, I don't think it helped that much. I will try again with the larger cone filte and 4" foil air hose (the 3" white air hose can't withstand the heat) attach to the cone filter. I hope it would help a bit.
