Holley 2-Piece Cast Aluminum Valve Covers - Polished Finish

If you're looking to give your LS engine a fresh new look, Holley's 2-Piece LS valve covers are just what you need! These stylish covers offer a straightforward upgrade without the fuss of complicated adapters or relocating coils. Designed with a modular approach, they feature an OE height, internally baffled design, and come with integrated coil mounts that fit both Gen I and Gen V style LS coil bodies. Plus, the vintage-inspired finned overcover conceals those unsightly coils and messy wiring, allowing you to enjoy the benefits of a coil-on-cover ignition setup while keeping things sleek and stylish.

Each coil cover boasts a simplified version of our Vintage Series style fins, which blend perfectly with other finned Holley accessories like our LS valley covers and 14" round air cleaners. You'll also appreciate the built-in provisions for spark plug boots and coil wiring, meaning no extensions or custom wiring are necessary!

When you purchase the 2-Piece LS valve cover set, you'll receive a low-profile billet oil fill cap, all the necessary hardware and spacers for mounting both versions of LS coil bodies, along with 12-point dress-up hardware and rubber grommets for the coil covers. Choose from five stunning finishes: natural cast, polished, satin black, factory orange, and gloss red (the black, factory orange, and gloss red options feature machined fins).
