Drop in K&N filter? It's an exact fit for a stock intake. It replaces your old air filter. It has a million mile warranty, and it's guaranteed that you will never need a new one again. I'm selling it cuz I just put on my AEM CAI, and I didn't want to post it on ebay just yet. I've used it for about four months, and I still have the original packaging and everything. It retails for roughly $40 i'm willing to sell it for $25 flat shipping included to anywhere in the US. Email me at davidlim@uiuc.edu if you're interested. Thanks!
