BMW M Power sticker included.

The signature BMW M Power sticker is provided with the airbox. If you plan on installing it, I recommend it is applied and re-cleared for a seamless finish.

Optional matching carbon snorkel.

The Karbonius design mimics the original BMW M snorkel, without the flap mechanism. If spec'e with the CSL airbox, it will come in matching weave pattern and finish.

Required hardware
