The Edelbrock sand‑cast aluminum coil cover for Gen III LS1 engines dresses up transplanted LS packages by allowing coils to mount directly to the underside of the cover, eliminating stock mounting brackets. It accepts GM coil PN 12558948 or equivalent aftermarket units such as MSD 8245. Built for clean custom and street‑rod installations; it is not intended to clear factory hose layouts on stock vehicles.
