Holley's cast aluminum valve covers for GM LS engines provide a fresh, refined look without the need to relocate the coils. There's no question the factory "coil on cover" design gives the LS that signature high-tech look, but the factory brackets and coil location leave room for improvement. Clean up that signature look with Holley's LS Valve Covers! They incorporate a radiused shape, angled coil mounting, and a billet fill cap. Plus, the coils mount directly to the cover with no need for a bracket in-between. They fit most popular LS series engines and come in Black Krinkle, Satin, Natural Cast, and Polished. Or, paint to match your vehicle's theme!
