Using this Perrin front strut tower brace is easy. First, gather all the included parts: the strut tower brace bar, left and right mounting feet, license plate frame, mounting hardware, and the instructions. Refer to the instructions carefully and start by attaching the left and right strut mounting feet to the appropriate locations in your engine bay. Then, secure the strut tower brace bar to the mounting feet using the provided hardware. Make sure all the connections are tight. When it comes to maintenance, regularly check the mounting hardware for any signs of looseness. You can clean the brace with a mild automotive cleaner to keep its wrinkle - black finish looking great. Remember, this brace is designed to work with OEM top - mount intercoolers. If you have an aftermarket intercooler, it may not fit, and we can't accept returns for incompatible braces. Also, on 2014 - 2016 Forester and Forester XT, it will press against the firewall plastic, so keep an eye on that area during use.
