Description

The STILLEN Rear Diffuser is engineered to enhance the rear styling of the 2014-2016 Lexus IS250 and IS350 models. The diffuser is finished in a sleek matte black, allowing it to seamlessly integrate with your vehicle's existing aesthetics or serve as a base for custom paint. The diffuser comes pre-equipped with genuine 3M automotive trim foam tape, the same type used by OEMs, ensuring a strong bond. Additionally, an adhesion promoter is included to facilitate a quick and easy installation process. The design specifically avoids the need for any cutting or modification to the vehicle's bumper, and the diffuser is removable if desired. Some applications may also include self-tapping screws for added security, ensuring the diffuser remains firmly in place. This rear diffuser is backed by a Limited Lifetime Warranty, underscoring STILLEN's commitment to quality and durability. The product is ready for direct installation out of the box, eliminating the need for further painting or extensive preparation, offering a convenient upgrade for Lexus IS owners looking to enhance their vehicle's appearance.
