Using this Cobb Redline carbon fiber engine cover is easy. First, make sure your Subaru WRX or STI is turned off and cooled down. Then, use the included black button - head hardware and COBB nylon washers to attach the cover to the engine using the satin black powder - coated aluminum brackets. The brackets are designed to make installation straightforward. When upgrading your intercooler, this cover can be installed right after the intercooler upgrade. If you're using it with the factory top - mount intercooler, just follow the same installation steps. As for maintenance, clean the cover regularly with a soft, dry cloth to keep the high - quality gloss finish looking great. Avoid using harsh chemicals as they might damage the carbon fiber. And remember, because the parts are hand - laid, there might be some natural variances in the weave pattern, which is normal and doesn't affect the performance of the cover.
