Folks have been pretty skeptical on the M2 forum about air intakes making power, so a lot of guys just run the stock intake with a drop in filter. For me, it’ll be stock & stock for now on!

I think this is the main concern of a dry filter in general. Usually the air filter oil is what helps capture very fine dust particles that may be small enough to pass through the actual filter media. In any case ill see how my OA looks when i do one. (Note, CTS is also a dry filter)
