Description

The Holley LS Lo-Ram EFI Intake Manifold Kit is meticulously crafted for GM LS Gen III and IV engines equipped with LS1/2/6 (cathedral port) cylinder heads. This intake manifold is optimized for forced induction applications, such as supercharged or turbocharged setups, delivering peak power between 7000-8000 RPM. Its modular design features a front-feed plenum entry, facilitating custom inlet duct and throttle body placement. The low-profile construction ensures compatibility under stock or mildly modified hoods, including 4th Gen Camaro and C5 Corvette models, without the need for modifications. The kit includes high-volume fuel rails with ¾”-16 O-ring ports (8 AN) and mounting hardware, accommodating both long (standard length) and short (Pico or LS7) fuel injectors. Constructed from cast aluminum with a natural finish, this intake manifold combines durability with performance.
