Description

The Alfissimo carbon fiber diffuser is designed as a direct replacement part for the Alfa Romeo Giulia QV, utilizing factory-matched 2x2 (3k Twill Weave) pre-impregnated Toray Dry Carbon Fiber. The diffuser features a Herringbone carbon fiber detail, mimicking the OEM GTA/m diffuser, and is finished with a UV protectant clear coat. Installation of this component is complex and requires the bumper to be removed from the vehicle. The process involves removing the old diffuser and spears, preparing the mating surfaces with minor sanding if necessary, installing the spears, then fitting the new diffuser onto the bumper. The bumper and diffuser assembly is then reinstalled onto the vehicle, which may require two people. Due to the complexity, professional installation is required and recommended to ensure proper fitment and prevent inconsistencies. Failure to have an experienced shop install the diffuser will void any warranty. Small adjustments, such as light sanding of the backside or removal of excess epoxy, may be necessary for a snug fit. These modifications are typically minor and do not involve significant alterations or the need for additional mounting mediums like glue. By purchasing this item, you acknowledge and agree to this information and the accompanying terms and policies.
