Product details

The all-new 2018-2021 Mustang 5.0L ROUSH V8 Cold Air Kit is more efficient air intake than the standard stock airbox. Cold air induction allows for latent potential in power and fuel efficiency that would otherwise be restricted, as well as providing reduced pressure drop. A custom tune is not required as this CAI system was engineered and tested specifically for this application, ensuring MAF signal performance matches factory settings. Included is an innovative airbox lid with see-through lens. Our dry filter is proven to retain its shape under high airflow, and is composed of an inner and outer layer of wire mesh for durability and reliable support of filtration media. The filter requires no oiling and is easily washable for re-use. Easy to install. ROUSH 5.0L V8 Cold Air Kit for 2018-2021 Mustangs increases performance and presence with no calibration required. Unlock latent power! ROUSH 2018-2021 Mustang 5.0L V8 GT Cold Air Kit
