This insert is a direct replacement for the stock lower grille found on 2013-2014 Mustangs (except GT500 models). The wide, open-mouth design allows for unobstructed airflow, thus improving cooling temperatures to the radiator and low temp radiator (if equipped). The ROUSH High-Flow Lower Opening is functional and looks good too, giving the front end of your Mustang a very distinct appearance. This lower opening is a great compliment to the ROUSH Upper Grille as well!

This component is made of injection-molded TPO (Thermoplastic Poly Olefin) plastic and is finished in a black stipple for an OEM appearance and durability. TPO plastic is tough, yet flexible, and is light-weight making this insert a must-have for a Mustang owner desiring superb appearance. Designed using OEM CAD data, this opening will also carry superior fit and finish. Installation of this piece can be done within 3 hours.

This kit will include all necessary mounting hardware, templates, and instructions. This piece is also backed by the ROUSH 90 Day Limited Parts Warranty.

Note: While this insert fits most 2013-2014 Mustangs, it will not fit GT500 models. This kit will also require some cutting of the factory front bumper.
