4x4AT's range of wind deflectors help to prevent the annoyance of dust, wind, direct sunshine or rain coming in to the BMW 1 Series's windows, in addition to reducing noise. Acting as shields, they are installed on the 1 Series's side windows and are available in sets of two or four. We offer a professional fitting service for all the BMW 1 Series accessories we sell, available at one of our UK installation centres, contact us for details.
