Holley 2-Piece Cast Aluminum Valve Covers - Gloss Red Finish

If you're looking to refresh the appearance of your LS engine, Holley's latest 2-Piece LS valve covers are a fantastic choice! These covers offer an easy upgrade without the need for complex adapter systems or the hassle of relocating coils. Designed with a modular approach, these valve covers maintain an OE height and come with an internally baffled base that includes integrated coil mounts for popular Gen I and Gen V LS coil bodies. Plus, the vintage-style finned overcover cleverly conceals those unsightly LS coils and messy wiring, allowing you to enjoy the full benefits of a coil-on-cover ignition setup without sacrificing style.

The coil cover boasts a simplified version of our Vintage Series fins that blend seamlessly with other finned Holley accessories, like our LS valley covers and 14" round air cleaners. You'll also find cast-in provisions for the spark plug boots and coil wiring harness, meaning no extensions or custom wiring are required!

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