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
