“Holley’s new 2-Piece LS valve covers are a great way to update the look of your LS engine without the use of complicated adapter systems or the hassle of remote coil relocation. These modular LS valve covers feature an OE height, internally baffled LS valve cover base with integrated coil mounts for popular Gen I and Gen V style LS coil bodies (coils not included), and a vintage style finned overcover that hides the unsightly LS coils and messy wiring harness – allowing the full performance benefits of coil-on-cover ignition setups without the robotic styling. Each modular coil cover features a simplified version of our Vintage Series style fins that seamlessly blends with other finned Holley dress-up accessories such as our LS valley covers and 14″” round air cleaners. The coil cover also features cast-in provisions for the spark plug boots and coil wiring harness so no extensions or custom wiring is required.”

“Holley’s cast aluminum valve covers for GM LS engines provide a fresh, refined look without the need to relocate the coils. There’s no question the factory “”coil on cover”” design gives the LS that signature high-tech look, but the factory brackets and coil location leave room for improvement. Clean up that signature look with Holley’s LS Valve Covers! They incorporate a radiused shape, angled coil mounting, and a billet fill cap. Plus, the coils mount directly to the cover with no need for a bracket in-between. They fit most popular LS series engines and come in Black Krinkle, Satin, Natural Cast, and Polished. Or, paint to match your vehicle’s theme!”

Based on our existing tall LS valve covers, the GM Licensed Tall LS valve covers eliminate the factory coil-on-cover look and instead feature prominent, cast-in graphics that are sure to dress up your engine bay and represent your loyalty to your favorite OEM brand.

The new GM Licensed Tall LS valve covers are available in five unique finishes to best fit your style: natural cast, polished, satin black, factory orange, and gloss red (all finishes have a precision machined logo surface aside from the polished version).

Let’s face it, nobody wants an ugly set of ignition coils sitting atop their newly dressed up engine. You can take the time and effort to relocate them or you get a set of TSP’s two-piece valve covers. The base has a tall internal height to allow for added valvetrain clearance and features provisions for mounting two of the most popular LS coil packs – no brackets required. It also features a baffled stock-style ventilation set-up. The coil cover features cut-outs for routing the wiring harness and spark plug wires and comes with a smooth top.
