Like jc5988 said it's a part in the air filter box that you can cut out and it just improves air flow, which results in a (very) small hp gain.

I know there are few (Eurocharged for example) but the AA is most common. BMS is a piggy back that you hook up to your DME (ECU). I don't have any experience with BMS but I heard good things, specially for the price. The AA tune is flash (you can do it yourself via Simon tool which costs extra, you can have it flashed at a AA dealer or you can mail your ECU to AA). I personally highly recommend the AA tune. If you want my opinion just get the AA tune, K & N drop in filter and the AA exhaust. That would the most cost efficient way to get the most out of this engine.

Funny, I searched "charcoal delete" on here and the answer to your question was on one of the first few threads. http://www.e90post.com/forums/showth...=carbon+filter
