Holley 2-Piece Valve Cover for GM LS Engines with Chevrolet Logo

Looking to give your LS engine a fresh new look? Holley's 2-Piece LS valve covers are the perfect solution! These covers allow you to upgrade your engine's appearance without the headache of complicated adapter systems or relocating coils. Designed with a modular approach, these LS valve covers maintain OE height and come with an internally baffled base. Plus, they feature integrated coil mounts that fit popular Gen I and Gen V LS coil bodies. The stylish "Chevrolet" branded overcover elegantly conceals the coils and messy wiring harness, letting you enjoy the benefits of coil-on-cover ignition setups without that robotic feel.

Each modular coil cover showcases a vintage "Chevrolet" logo that pairs beautifully with various GM licensed Holley products. The design also includes provisions for spark plug boots and coil wiring harnesses, eliminating the need for extensions or custom wiring!

When you choose the 2-Piece LS valve cover set, you’ll receive a low-profile billet oil fill cap, all the necessary hardware and spacers for mounting both versions of LS coil bodies, and 12-point dress-up hardware along with rubber grommets for the coil covers. You can pick from five unique finishes: natural cast, polished, satin black, factory orange, and gloss red (with black, factory orange, and gloss red sets featuring machined fins).
