I can put a drop in K&N airfilter on my 2012 forester non turbo without changing anything correct?

so if he doesn't adjust the mass airflow sensor, does he have to worry about the engine running lean?

I see lots of folks advise against a performance intake kit on the turbo's unless you tune for it afterwards.

it seems none of us knew this in the late 90's when everyone was throwing new air filters in their Accords.
