Important Notes

Body kits are unfinished products and require professional preparation. This component arrives in its raw plastic form, allowing your paint specialist the freedom to choose their preferred primer for optimal results. These diffusers come in a matte-like finish and can be installed without being painted for a clean aesthetic. Professional installation is highly recommended to ensure the perfect road profile. Parts that have been modified or painted after delivery are ineligible for returns.
