Using this GrimmSpeed bumper bar is straightforward. First, make sure your 2015 - 2021 Subaru WRX or STI is parked on a flat surface and the engine is off. Then, carefully install the bumper bar following the included instructions. When using the tow hook, remember it's only for the license plate relocation kit and not for vehicle recovery. As for maintenance, regularly check the mounting plates and the coating. If you notice any chips in the wrinkle black coating, touch it up with a suitable powder - coat paint to prevent rust. Also, since this bar is designed for the GrimmSpeed Front Mount Intercooler Core, don't try to use it with other aftermarket intercooler cores as it may not fit properly.
