Using the Perrin pulley cover is a great way to upgrade your Subaru WRX's engine look. First, make sure your car is a 2022 - 2025 Subaru WRX and you don't have a PERRIN Air Oil Separator (AOS) as this cover won't work with it. To install, use the provided bracket, tools, and hardware following the included installation guide. It's a direct replacement for the factory pulley cover, so it should fit right in. When it comes to maintenance, since it has a powder - coat finish, you can simply wash it with mild soap and water to keep it looking clean. Avoid using abrasive cleaners as they might damage the finish. If you notice any signs of corrosion or damage, contact the manufacturer according to the warranty instructions.
