Wind Tunnel Tested Center Louver for the 2000-2006 BMW E46 M3 and Non M3's. On the M3 these are designed to be installed on the forward part of the raised center section of the hood. This places the extractor just behind the radiator in the optimum position. This allows the rear edges to line up with the rear edges of the side louver kit. On the Non M3's these are designed to be installed more forward on the hood just behind the radiator with the front edge lined up with the front edges of the side louver kit.
