An exhaust heat shield, also called heat shroud, is a device that shields heat-sensitive components from damage by absorbing heat radiation of the exhaust system. It is also used as a heat barrier that provides increased engine power by reducing the engine bay temperature and minimizing the intake air temperature which goes into the combustion chamber. A cracked or rusted exhaust heat shield will not be capable in preventing heat from escaping out of the system, contacting to the other components which may cause them to overheat and resulting to decreased engine power.
