Thanks Tom for the clarification. Any performance difference between the charcoal lined and paper filter?...
I understand what you're saying about the adapter but the description on the EAS website for the adapter is slightly confusing me... "Macht Schnell - S65B40 M3 High Performance Air Filter Adapter (Euro Models & 2010+ US Models, not required on 2008-2009 US M3 models)"
Unless there are two air filter adapters...1) to allow fitment of '08 filters into later US models and euro models and 2) to allow fitment of +'10 filters/euro filters into '08-'09 models... could you provide a little bit more clarity? really appreciate it.
