Not sure if you guys have seen this yet either, but we have been chopping the hell outta our airboxes until a real intake is available. AEM has one coming soon for the Redline, and supposedly so does K&N. I didn't see the Cobalt listed, but I don't think I looked either. There are many threads available at the Redline forums about this subject as well. So if anyone is interested in it, pop on over and check it out, if nothing else it really lets the supercharger scream loud!
