Using your Noble RD2 style hood scoop is easy. First, when you get the product, it's ready to assemble. You can decide whether to include the grill to create a unique look for your 2022 - 2025 Subaru WRX. For installation, begin by taking off the original scoop from the underside of the hood. Then, bolt on the new scoop. Be careful not to over - tighten the screws; just make them hand - tight. It's a good idea to have a professional handle the installation if you're not confident. When it comes to maintenance, since it's made of plastic, you can clean it with a mild car wash soap and a soft cloth. Avoid using harsh chemicals that might damage the paint - matched finish. With proper care, your hood scoop will keep looking great and enhance your car's style for a long time.
