The ROUSH 5.0L V8 Cold Air Kit for 2018–2021 Mustang replaces the stock airbox with a more efficient intake that feeds cooler, denser air for improved power and reduced pressure drop without requiring a custom tune. The system maintains MAF signal performance to match factory settings and includes an airbox lid with a see‑through lens. The washable dry filter uses inner and outer wire mesh layers for shape retention under high airflow and requires no oiling, making maintenance straightforward.
