Holley 2-Piece Cast Aluminum Valve Covers - Satin Black Finish

Looking to refresh the appearance of your LS engine? Holley's new 2-Piece LS valve covers are an excellent choice! These covers provide a stylish update without the fuss of complicated adapter systems or the need to relocate your coils. Designed with a modular approach, these valve covers maintain OE height and feature an internally baffled base. They come equipped with integrated coil mounts that fit popular Gen I and Gen V style LS coil bodies. Plus, the vintage-style finned overcover elegantly conceals those unsightly LS coils and messy wiring, allowing you to enjoy the benefits of a coil-on-cover ignition setup without compromising on style.

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

When you purchase the 2-Piece LS valve cover set, you’ll receive a low-profile billet oil fill cap, along with all the necessary hardware and spacers to mount both versions of LS coil bodies. We've included 12-point dress-up hardware and rubber grommets for the coil covers, ensuring you have everything you need for a smooth installation. Choose from five unique finishes: natural cast, polished, satin black, factory orange, and gloss red (with black, factory orange, and gloss red options featuring machined fins).
