Using your Perrin License Plate Delete is a breeze. First, gather all the included hardware, which are the black - finished screws and wellnuts. Then, place the license plate delete over the front license plate holes on your 2006 - 2017 Subaru WRX or STI. Align it properly and use the screws and wellnuts to secure it in place. Make sure it's tightly fastened to avoid any rattling. When it comes to maintenance, just use a mild car cleaner and a soft cloth to wipe it down regularly. This will keep the anodized black finish looking great. Avoid using abrasive cleaners or rough materials that could scratch the plate. Also, check the hardware periodically to ensure it's still tight. If you have any questions or encounter issues, refer to the included warranty and instructions.
