Using the Noble V1D Vortex Generator is a great way to add style to your 2022 - 2024 Subaru WRX. When installing, remember to clean the roof area well and install it at a temperature between 70 - 80 degrees. Get a friend to help you test - fit it first. After installation, wait for the bond to set. It forms a solid bond in 24 hours and a full bond in 72 hours. As for maintenance, just clean it regularly with a mild car cleaner. Don't forget, the roof spoiler is sold separately, so if you want that, you'll need to buy it on your own.
