Holley 2-Piece Cast Aluminum Valve Covers - Factory Orange Finish

If you're looking to give your LS engine a fresh new look, Holley's 2-Piece LS valve covers are a fantastic choice! These covers make it easy to update your engine's appearance without the headaches of complicated adapters or relocating coils. Designed with a modular approach, these valve covers feature an OE height and an internally baffled base that includes integrated coil mounts for both Gen I and Gen V style LS coil bodies. Plus, the charming vintage-style finned overcover does a great job of concealing those unsightly coils and messy wiring, all while allowing you to enjoy the benefits of coil-on-cover ignition setups without the robotic aesthetic.

Each coil cover showcases a simplified version of our Vintage Series fins, seamlessly coordinating with other finned Holley accessories, like our LS valley covers and 14" round air cleaners. You’ll also appreciate the thoughtful design that includes cast-in provisions for spark plug boots and coil wiring, eliminating the need for extensions or custom wiring.

This 2-Piece LS valve cover set comes complete with a low-profile billet oil fill cap, all the necessary mounting hardware, spacers for both types of LS coil bodies, and stylish 12-point dress-up hardware along with rubber grommets for the coil covers. Choose from five unique finishes: natural cast, polished, satin black, factory orange, and gloss red (the black, factory orange, and gloss red options feature machined fins). Keep an eye out for the polished and black versions coming soon!
