The Holley 241-377 valve covers are a 2-piece design for GM Gen V LT engines that hides the ignition coils under a script logo coil cover for a cleaner engine bay. A die cast aluminum base mounts the coils, and the separate top bolts on over them, so the coils stay serviceable while the wiring is tucked out of sight. The satin black finish lets you match the covers to the rest of the build.
