A true Mustang enthusiast doesn't just pay attention to the outside appearance of their muscle car, but to the vehicle's looks in the engine compartment, too – and that's where 2015 Mustang valve covers come in. Made to enhance the under-the-hood slickness of your sixth generation 'Stang, these fixtures come in a choice of black or chrome finishes, depending on whether you're aiming for a "stealth" or an "ultramodern" look. These covers – which also help to keep potentially sensitive engine components clean and protected – are enhanced even more with the high-profile logos of famous suppliers, including Ford Racing and Roush Performance. Most come in a kit of two covers to provide full coverage and an all-round aesthetic upgrade straight out of the box.
