Using this Perrin Front Strut Bar is easy. First, gather all the included parts: the strut tower brace bar, left and right mounting feet, license plate frame, mounting hardware, and instructions. Refer to the instructions to install the strut bar on your vehicle. Make sure to follow the steps carefully. When installing, be aware that on 2014 - 2016 Forester and Forester XT, it may press tight against the firewall plastic. Also, this bar is designed to work with the OEM Top Mount Intercooler. If you have an aftermarket intercooler, it might not fit. Don't try to force it. As for maintenance, keep it clean. You can use a mild soap and water solution to clean the bar and the mounting feet. Check the mounting hardware regularly to make sure it's tight. If you notice any signs of wear or damage, contact the manufacturer for advice.
