Thanks guys! I bought the BMC filter b/c I am getting the car with the Dinan ECU flash so I figured the engine could use some better air flow. I have read that since the new OEM filter MY 2010+ don't have the charcoal layer anymore, that they flow very well, so I just don't know if I should keep the BMC or stay stock. MY gut and research says the BMC will flow better, maybe let in a little more dirt, but that should be relatively negligible. Thanks for the replies!
