I think you want the "M aerodynamics" as the bumper flares out a little under the fog lights as in your picture. I just bought the entire kit at a BMW dealership for my 2004 325ci and the receipt said M aerodynamik. It included the front bumper, fog lights, side skirts and rear bumper. I had to pay extra for the rear bumper insert to accomodate the single dual exhaust pipes.
