2021-2024 Kia K5 Aerotune Rear Diffuser - 1 Piece (S) - 118175

Disclaimer:

Duraflex diffusers are aftermarket aerodynamic accessories designed specifically for off-road and show use. As with all Duraflex products, these diffusers are not intended for use on public roads, and Duraflex disclaims any responsibility for damage or injury resulting from their use. Due to the nature of fiberglass and the manufacturing processes involved, Duraflex diffusers are not ‘direct bolt-on’ parts and often require extensive preparation, such as sanding, fitting, or custom bodywork. Common issues with fiberglass diffusers include potential warping, cracking, or fitment challenges, especially if they are not handled or installed properly.

Duraflex diffusers generally fit below the rear bumper, and in many cases, the bumper may need to be modified to accommodate the diffuser. It's important to note that many diffusers are designed to fit specific bumpers, certain trims, or aftermarket styles, so careful attention should be paid to the design and compatibility when selecting and installing a diffuser.

In terms of installation, Duraflex diffusers typically require separate mounting hardware, which is not included in the package. This hardware often includes L-brackets, bolts, screws, washers, and other fasteners. L-brackets are commonly used to attach the diffuser securely to the vehicle's chassis or bumper, while bolts and screws ensure a tight fit. In some cases, additional supports or reinforcements might be necessary, depending on the design and the specific fitment of the diffuser. Since this hardware is not included, installers will need to source the appropriate materials separately, ensuring they are compatible with both the diffuser and the vehicle.

For optimal results, Duraflex recommends professional installation by a custom shop experienced with fiberglass components and aftermarket accessories. Traditional auto repair shops may lack the expertise to properly handle the nuances of fiberglass fitment and hardware requirements. Like all Duraflex body kits and accessories, these diffusers are designed strictly for off-road and show use. Due to strict Department of Transportation (DOT) regulations, most Duraflex diffusers are not street legal. Duraflex does not endorse or recommend using these diffusers on public roads or highways.
