With a black wrinkle or polished finish, these Mopar Performance high-strength cast aluminum covers are more rigid than standard aluminum covers for improved leak prevention.
Sold "as cast," so you can set up the breathers the way you want them, and there's no paint to remove if welding is done. Mopar Pentastar logo is cast into each cover. Cast covers are more rigid than stamped steel which helps prevent valve cover leaks.
