Up until recently, the Macht Schnell S65B40 filters were limited to US models, european models were left with very little selection for a solution on a performance air filter.
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. Constructed from high quality ABS plastic, these will fit into the centering pin indentation on your filter for a perfect fit.
