Holley aluminum LS valve covers will give your Chevrolet LS Series engines a totally new look. Manufactured from cast aluminum, they come in four different finishes, and feature a billet aluminum oil fill cap. Some valve covers in this series eliminate the need for the factory ignition coil bracket. Instead, the coils bolt directly to the valve covers for a nice angled look! Holley aluminum LS valve covers reuse the factory gaskets and bolts, will work with .750 in. lift camshafts using stock-style rocker arms, and fit all ignition coils with 72mm spacing.

Holley LS throttle bodies are unquestionably the biggest bore and most feature-loaded option available. Holley went back to the drawing board and built the ultimate air valve for your LS engine. They are available with huge 105mm or 95mm bores--and low rpm, drive-friendly tapers. The 105mm version is designed for drag race applications when wide-open throttle is all that matters. Features like idle bleed adjustment, TPS clocker, and PCV passage defeat valve units, making them the ultimate throttle bodies for ease of installation and tuning. Regardless of whether you have a turbo, supercharger, or a big cam engine sucking gulps of air, Holley LS throttle bodies are manufactured from high-grade billet aluminum, and black anodized to give them a modern tech look, they're maximized for your application.

Holley LS Modular Lo-Ram EFI intake systems have a top-feed plenum entry configuration, designed to allow the currently available Hi-Ram 105mm plenum tops to be fitted to a low-profile base intake manifold. The short runner, low-profile base intake manifold intended for forced induction applications and was conceived to package with an air-to-water plenum-mounted intercooler—with a shorter overall height than is possible with other existing intake manifolds. Using a modular design, the top-feed plenum configuration with 105mm top keeps the overall height at just 9.07 in.! Additional features and specs include: * Cast aluminum construction * Modular design allows the use of the included top-feed plenum entry * Designed for GM LS Gen III and IV engines equipped with GM LS1/LS2/LS6 (cathedral port) cylinder heads * Will also work with OE or aftermarket cylinder heads * Designed for forced induction (supercharged or turbocharged) engine applications with peak power at 7,000 to 8,000 rpm, depending on application * Low height to aid the packaging of a plenum-mounted air-to-water intercooler in a top-feed configuration (or to fit under a stock or mildly modified hood in the front-feed configuration) * High-volume fuel rails and mounting hardware included with 3/4 in.-16 O-ring ports (8 AN) * Fuel rail kits come with two sets of brackets—a set for long (usually standard length) fuel injectors, and a set for short (such as Pico or LS7) fuel injectors

Holley LS Modular Lo-Ram EFI intake manifolds are designed for GM LS Gen III and IV engines equipped with GM LS1/LS2/LS6 (cathedral port) cylinder heads. These intake manifolds will work with OE or aftermarket cylinder heads. The Lo-Ram intake manifolds are designed for forced induction (supercharged or turbocharged) engine applications and a 105 mm throttle or similar models. The base intake manifold is designed with a lower overall height to fit under a stock or mildly modified hood in the front-feed configuration. The modular design allows the use of front-feed plenum entry, while intake design facilitates custom inlet duct and throttle body placement. Additional features and specs: * Cast aluminum construction with satin silver finish * Modular design allows the use of front-feed plenum entry * Clears 4th Gen Camaro and C5 Corvette cowls and hoods without modification * With forced-induction and the short runner length the engine rpm at which peak power occurs is more likely to be coupled to the supercharger or turbocharger being used * High-volume fuel rails and mounting hardware included with 3/4 in.-16 O-ring ports (8 AN) * Fuel rail kits include two sets of brackets; a set for long (usually standard length) fuel injectors and a set for short (such as Pico, or LS7) fuel injectors

Holley EFI LS Hi-Ram intake manifold bases are cost-effective alternatives to fabricated sheet metal for high performance applications where induction system height is not limited. Coupling these cast aluminum Hi-Rams with the high flowing LS-style cylinder heads has outstanding potential for N/A and forced induction applications at a budget-minded cost. These modular lower manifolds accept a wide range of carbureted and EFI tops, making them attractive to builders and fabricators as the perfect foundations for custom induction systems. Fuel rails are included and machined for -8 AN O-ring fittings with passages large enough to accommodate high fuel flows and dampen pressure pulsations in the fuel system. The aggressive, bold, race-bred styling of Holley GM LS modular Hi-Ram lower manifolds will make bad intentions clear for drag race, muscle car, marine, off-road, sand rails, pulling trucks, track, and street-rod applications.

Developed with performance in mind, Holley EFI LS single plane split-design race intake manifolds feature a race bred, 2-piece split design that was previously found only on the most expensive race intakes. These manifolds will fit GM LS Gen III engines with cathedral port heads for high performance/racing engine applications with 5.3 to 6.2 liter displacement and maximum engine speeds of 6,000 to 7,000 rpm, depending on the engine combination. The single-plane design provides optimal performance across the rpm spectrum, while the split feature, which allows disassembly of the intake for direct access to internal plenum and port surfaces, makes custom porting and matching a snap. Shoulder bolt locators and an O-ring seal makes reassembly simple and precise.
