Overview

The Roush High Flow Lower Grille is a performance-oriented exterior upgrade designed to enhance the front-end aesthetics of 2018-2023 GT and EcoBoost Mustang models. This component features a larger opening to improve airflow to the radiator or intercooler, helping to lower engine temperatures.

Constructed in the USA from injection-molded TPO, the grille offers high-strength durability and impact resistance with a grainy black textured finish. It includes an optional blackout graphic for a refined, integrated appearance.
Show original supplier description
The Roush High Flow Lower Grille is a direct-fit performance upgrade for 2018-2023 GT and EcoBoost Mustang models, specifically engineered to provide an aggressive front-end aesthetic. By incorporating a larger opening compared to the factory component, this grille increases airflow across the radiator or intercooler, which is particularly beneficial for supercharged or turbocharged engine setups. Manufactured at Roush's own facility in the USA, the grille is produced using high-pressure injection molding and original Ford CAD data to ensure precise fitment. It is crafted from lightweight, high-strength thermal plastic olefin (TPO), a material chosen for its superior impact resistance and durability against the hazards of daily driving. The exterior is finished in a black, stipple texture that mimics OEM styling standards. Installation requires minor trimming and approximately two hours of labor, with light-to-moderate mechanical skills recommended. Note that this part does not fit Shelby GT350 models. For proper integration, appearance, and structural mounting, this grille requires the Roush Chin Spoiler & Wheel Shroud 3-Piece Aero Kit, part #422082 (sold separately). Attempting to install the grille without this mandatory aero kit will prevent correct fitment.
