These JDM - style grille pinstripes are a great way to decorate your Subaru WRX from 2022 to 2025. When you get them, they come in pairs, and one is a backup. Don't mix different colors. Before you start installing, clean the grille and the area around it with a microfiber cloth and detailing spray. Try to install them when it's between 70 - 80 degrees and not in direct sunlight. Start at a corner of the grille and gently guide the pinstripe across without stretching it. It should fit the grille perfectly. As for maintenance, just keep the grille clean, and the pinstripes will look great for a long time.
