Holley 2-Piece Cast Aluminum Valve Covers - Natural Finish

If you're looking to refresh the appearance of your LS engine, Holley's new 2-Piece LS valve covers are an excellent choice. They provide a stylish update without the fuss of complicated adapter systems or the need for remote coil relocation. These modular valve covers come with an OE height and feature an internally baffled base, complete with integrated coil mounts tailored for popular Gen I and Gen V LS coil bodies. Plus, the vintage-style finned overcover cleverly conceals those unsightly LS coils and messy wiring, allowing you to enjoy the full benefits of coil-on-cover ignition setups while maintaining a classic look.

Each modular coil cover showcases a streamlined version of our Vintage Series fins, blending 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 harness, meaning no extensions or custom wiring are necessary.

Your purchase of the 2-Piece LS valve cover set includes a low-profile billet oil fill cap, all the hardware and spacers needed for mounting both versions of LS coil bodies, and stylish 12-point dress-up hardware along with rubber grommets for the coil covers. You'll have the option to choose from five unique finishes: natural cast, polished, satin black, factory orange, and gloss red (with black, factory orange, and gloss red featuring machined fins). Keep an eye out for polished and black versions coming soon!
