Using your Perrin License Plate Delete is a breeze. First, gather all the items in the box, including the license plate delete, the two #14 Phillips Truss head screws, and the instructions. Park your 2002 - 2005 Subaru WRX or 2004 - 2005 STI in a safe and flat place. Then, take the license plate delete and align it with the front license plate holes on your bumper. Use the provided screws to attach it securely. Make sure it's tightly fixed to avoid any rattling while driving. When it comes to maintenance, simply use a mild soap and water solution to clean it. Avoid using abrasive cleaners as they can damage the anodized black finish. If you notice any scratches or damages, contact the manufacturer for advice on possible repairs or replacements. Keep in mind that this product is designed specifically for the mentioned Subaru models, so don't try to install it on other vehicles.
