      Description

      Functional Aerodynamic Enhancement. The Stealth Diffuser; Main Center is engineered to improve airflow beneath the vehicle by smoothing and diffusing air from the differential to the rear of the Mustang. This reduces turbulence and enhances aerodynamic efficiency, benefiting vehicle stability and performance, particularly at higher speeds.

      Construction and Appearance. Constructed with a durable HDPE main panel finished to automotive standards and complemented by an aluminum belly pan for structural integrity. Finish options include raw standard aluminum with a natural look and black powder-coated aluminum for a sleek, protective appearance. The aluminum attachment plate may have minor manufacturing marks that remain hidden once installed.

      Installation. Designed for straightforward installation by bolting directly onto the factory rear premium valance without major modifications. The diffuser fins ship separately and require assembly using a Philips head screwdriver or drill.

      Application. Specifically designed for 2015-2017 Mustang GT and EcoBoost Premium models with dual-tip exhausts. It does not fit non-premium valance configurations or models with quad-tip exhaust setups, ensuring precise compatibility and optimal fitment.
