Set your car apart from the crowd with the ROUSH Lower High-Flow Grille Opening. New for 2018-2021, this ROUSH part alters the Mustang's overall front end appearance. By overlapping the lower portion of the fascia, this piece blacks out more of the front end, including an optional-use blackout graphic for above the opening to complete the look. The larger opening allows airflow to be directed to the intercooler systems of supercharged and turbocharged vehicles.The ROUSH Lower High-Flow Grille Opening is made from injection-molded TPO (Thermoplastic Poly Olefin) with a black stipple finish for a factory look and lasting durability. This insert is designed around original manufacturer CAD data for optimum quality and fit. As a result, installation is quick and easy, and unlike competitor kits, part trimming and sanding is not required.

Mustang Lower High-Flow Grille fits most GT & EcoBoost models. Allows for better powertrain cooling. Injection-molded & OEM CAD designed for precise fit.
