Aero Function diffusers are aftermarket aerodynamic accessories designed specifically for enhancing style and performance. These diffusers are not “direct bolt-on” parts and may require significant preparation, such as sanding, fitting, or custom bodywork. Common installation challenges can include potential warping, cracking, or fitment issues if the diffuser is not handled or installed correctly.
Aero Function diffusers are generally installed below the rear bumper, and in many cases, the bumper may need to be modified to ensure a proper fit. It’s important to select a diffuser that is compatible with specific bumpers, trims, or aftermarket styles to avoid fitment issues.
Separate mounting hardware, such as L-brackets, bolts, screws, washers, and fasteners, is typically required but not included in the package. L-brackets help attach the diffuser securely to the vehicle’s chassis or bumper, while additional supports may be needed depending on the design and fitment. Installers will need to source the necessary materials separately to ensure compatibility with both the diffuser and the vehicle.
For the best results, Aero Function recommends professional installation by a custom shop experienced in aftermarket accessories. Many standard auto repair shops may lack the expertise to handle the specific fitment and hardware requirements for these diffusers.
Please note that these diffusers are intended strictly for off-road and show use. Due to strict Department of Transportation (DOT) regulations, most Aero Function diffusers are not street-legal. Aero Function does not endorse or recommend using these diffusers on public roads or highways.
