They factory sill plates Porsche uses on the 991 series 911 are attractive enough, with a recessed metal logo. Unfortunately, the plastic part of the sill plate is sensitive to scuffs and scratches. These adhesivebacked stainless steel overlays are a great way to improve the look of your interior, while hiding sill plate scratches and preventing new ones. Comes as a pair, ready to install with doublesided adhesive already applied.
