Holley 2-Piece LS Valve Covers with Chevrolet Logo

If you're looking to give your LS engine a fresh new look, Holley's 2-Piece LS valve covers are just the ticket! These stylish covers let you update your engine's appearance without the need for complicated adapters or the stress of relocating coils. Designed with a modular approach, these valve covers maintain the OE height and come with an internally baffled base that integrates coil mounts for popular Gen I and Gen V LS coil bodies. Plus, the sleek "Chevrolet" branded overcover neatly conceals the coils and any messy wiring, allowing you to enjoy the performance of coil-on-cover ignition setups without the robotic look.

Each coil cover showcases a bold vintage "Chevrolet" logo, perfectly complementing other GM licensed Holley products. With built-in provisions for spark plug boots and coil wiring harnesses, there’s no need for extensions or custom wiring. It’s all about simplicity!

When you purchase a set of these 2-Piece LS valve covers, you'll receive a low-profile billet oil fill cap, all the necessary hardware, spacers for both versions of LS coil bodies, as well as 12-point dress-up hardware and rubber grommets for the coil covers. You can 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).
