Ready to ditch your factory airbox in your BMW F3X 340i or 440i B58? aFe's intake system uses a 7" tall conical 360 degree radial flow performance air filter giving you the max airflow and performance out of a closed intake system.

When it comes to design and construction, nothing was overlooked by afe's engineers. This intake system uses a dyno tuned intake tube guaranteed for perfect fitment along with a urethane plug if you want to block off your auxiliary air inlet.

Fitment Note:
This item will not fit convertible models due to the factory strut brace.

Notes
