Roush Quarter Window Scoops are made from Blow Molded ABS with OEM levels of durability and impact resistance. The Roush Quarter Window Scoops are designed around original manufacturer CAD data for optimum quality and fit to ensure a quick and easy installation. All mounting hardware and adhesive tape is included for quick and easy installation. These scoops come painted in a gloss black finish. Roush does not offer these in any other pre-painted factory Ford color, nor is there a primed option. The gloss black finish will match both Black (UA) and Shadow Black (G1) paint finishes, or provide a nice contrast on most other factory colors. The part number for this item is Roush 421881 and it fits 2015-2018 Ford Mustang FastBack models. Price is for both sides.
