Macht Schnell S65B40 High Performance Air Filter Adapter - E9X M3 (Euro Models & 2010-Up US Models)

BMW changed the centering pin design in the E9X M3 factory airbox lid partway through production, and EU-spec cars used a different pin location from the start. Without the correct adapter, the Macht Schnell S65B40 High-Performance Filter will not align precisely in the airbox lid on these builds — resulting in a potential bypass leak. The Macht Schnell Filter Adapter fills that centering pin indentation and provides a positive, rattle-free fit between the filter and the lid.

Machined from high-quality ABS to the exact geometry of the S65B40 airbox on Euro models and 2010+ US E9X M3 builds. Required for: all EU-spec E9X M3 builds and 2010+ US-spec E9X M3 builds. Not needed for 2008–2009 US-spec M3s. Sold as a set. Used with the Macht Schnell S65B40 M3 High-Performance Filter (sold separately).
