Stock 335i does not have any air scoops behind the actual kidney grille (which is the upper roundish pair of openings).
Meanwhile, stock 335i has black plastic air scoops (and ducts) behind the lower meshes on the left and on the right. All cars have air ducts that lead from lower side-meshes to the front brakes (you can see the other end of the duct inside each of the front wheel wells). Also, Sport and M-Sport cars have an additional scoop+duct on the passenger side that leads to the oil cooler installed in front of the right-front wheel. Finally, Performance Package 2 cars have an additional scoop+duct on the driver side that leads to the additional water cooler.
