Holley 2-Piece LS Valve Covers with Chevrolet Logo

Looking to give your LS engine a fresh look? Holley's new 2-Piece LS valve covers are the perfect solution! You won't have to deal with complicated adapter systems or the hassle of relocating coils. These modular valve covers come with an OE height and an internally baffled base, complete with integrated coil mounts that fit popular Gen I and Gen V LS coil bodies. Plus, the stylish "Chevrolet" branded overcover neatly conceals those unsightly LS coils and messy wiring, letting you enjoy all the performance benefits of coil-on-cover ignition setups without the robotic look.

Each coil cover showcases a vintage "Chevrolet" logo that pairs beautifully with various other GM licensed Holley products. You'll also find cast-in provisions for spark plug boots and the coil wiring harness, which means no extensions or custom wiring are needed!

Every set of these 2-Piece LS valve covers comes with a sleek 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 unique finishes: natural cast, polished, satin black, factory orange, and gloss red (the black, factory orange, and gloss red sets feature beautifully machined fins).
