I just did mine. You need a dremel tool to make it externally unnoticable. I don't have a dremel, but used a 1/8" upcut router bit to trim awat around the charcoal element.
The charcaol element piece has markings on it, looks like the OEM part number 661 706 2. It's built in to a spacer that goes between the two halves of the airbox, and is glued to one half of the airbox shell. I removed it with a couple of putty knives/wide chisels without doing any damage to the airbox or the flange of the part itself.
To do this mod, you need a T25 torx driver, a couple of 1" chisels, a dremel, and some finishing files. Took me about 20 minutes.
