Authentic Audi All-Weather Floor Mats feature a deep ribbed channel design to protect the floor carpeting from water, sand, mud, and snow. Our rubber mats conform to the vehicles' exact contours for maximum protection of the interior. Authentic mats possess safety features like positive retention anchors and an exclusive chevron w/nib design for added security. Rubber mats are black or clay, with contrasting A6 logo to complement your interior. (Except A6 4.2 model.) New rubber mats may emit a naturally occurring-odor. We recommend washing mats with a light detergent prior to installation. (Set of 4.)
