When installing carbon fiber interior accessories, first use a professional pry bar or disassembly tool to carefully remove the corresponding original parts of the vehicle, taking care not to scratch the interior. After disassembly, clean the residual dust and debris from the installation position to ensure the surface is clean and flat. Next, align the carbon fiber accessory with the original vehicle's clips or fixed positions, press or fasten it evenly with force until it is completely clamped and fixed. After installation, check if the accessory is stable, whether there is any looseness or gap, and ensure it fits perfectly with the interior without affecting normal use functions.
