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