Using this Verus OEM Hood Scoop Block - Off Kit is easy. First, gather all the included hardware. Then, carefully place the block - off over the hood scoop of your 2008 - 2014 Subaru WRX or STI (GR/GV). Use the provided hardware to secure it in place. No need to cut or drill, so you won't damage your car. When installing, make sure the block - off is properly aligned to ensure the best performance. As for maintenance, since it has a black powdercoat finish, it's quite durable. But you can clean it with a mild soap and water solution to keep it looking good. Avoid using harsh chemicals as they might damage the powdercoat. Also, regularly check the hardware to make sure it's tight, especially after driving on rough roads or in extreme conditions. This will help keep the engine bay dry and clean and maintain the aerodynamics and cooling benefits of the kit.
