The MAF screen is supposed to smooth out the airflow in to the engine. Taking it out can cause idle problems for some people. For a stock airbox such as yours, I'd say leave it in.

Also my G/F has a cavalier and we have been having fun with that (headers, catback exhaust, CAI, ect.) and when we put on the CAI it sounds great at WOT and i was wondering if i gutted the airbox would i be able to get some extra sound out of it or would i have to do the CAI to get the nice wistleing noise??

Yes, usually people pull the screen out when they have a nice smooth intake pipe running in to the thottle body, so the airflow is already laminar. On a stock airbox, the airflow isn't as smooth, so the screen helps keep it laminar.

I'd say leave it in.

As for the CAI thing, with a gutted box and a K&N, you should notice a nice sound difference.

I have the stock "pipe" and gutted airbox. With the screen pulled, I have no idle problems.

You can pull yours, see how it acts, and put it back in if necessary.

Also do they make a intake tube like for example the one that was talked about from autozone would that go from my T/B to the airbox and fit into everything?

You can get one from Autozone, I believe it is a Spectre Intake tube, its in an oragne package. For the most part you won't have to do much. Just cut part of the end off so you can fit your air filter in there. You might also want to drill a hole in the filter to plug the AIT (Air Intake Temperature) sensor in. That'* what I have on my Bonnie and I could REALLY feel the difference. The air filter I used was a K&N X-Stream cone, I think the part number was RX4750, you might wanna double check that with somebody else though. I could really hear and feel the difference when I moved to the CAI. I left my MAF screen on because I didn't really want to mess with it and stuff. Good luck with your modding.

yup a rice pipe as it is known here will help you alot. All you need to do is cut the end of the pipe (depending on filter length) and get a coupler to attach from the TB to the pipe. you car use the existing hole in the pipe for the IAT, that is where i have mine. You can just go to Pepboys and look at there K&N selection and pick out an approiate filter, I have a 9'' cone on my car

When removing the MAF Screen.. if your idle become lopy like a big cam, that means you have a vacuum leak. Did that to me, too, then I traced it down to my vacuum leak.
