Macht Schnell has released their euro S65B40 filter adapters to allow the Macht Schnell S65B40 M3 High Performance Air Filters to fit properly within euro airboxes. These are also required on 2010+ models due to a change in production on the factory airbox. Constructed from high quality ABS plastic, these will fit into the centering pin indentation on your filter for a perfect fit.
