GM LS2, LS3, and LS7 Aluminum Engine Coil Covers - Natural Finish If you desire a clean and customized look to your engine compartment, our new Atomic LS coil covers are designed to fit over the valve covers and coil assemblies to effectively hide the coil packs and wiring. Bare coil covers allow you to customize them to your liking. The cast aluminum covers align with the Atomic Smart Fuel Rail assemblies and provide a completely smooth contoured finish to the edge of the valve cover. The Atomic Coil Covers will work with OEM coils as well as MSD's Multiple Sparking Coils.
