The Lo-Ram Intake Manifold Kit LS1/LS2/LS6 Frt Feed by Holley is engineered for serious LS platform builds where low-profile hood clearance and maximum airflow are non-negotiable. This front-feed design addresses a critical pain point for engine swaps and high-output builds: traditional tall intake manifolds consume valuable underhood real estate and create fitment headaches with modern hood panels. Whether you're building a restomod, track car, or street machine, this manifold delivers the breathing efficiency your LS engine demands without compromise on packaging.
Holley's lo-ram profile substantially reduces vertical height while maintaining runner geometry optimized for velocity and plenum distribution across all six cylinders. The front-feed fuel inlet configuration simplifies fuel line routing and works seamlessly with both carbureted and fuel-injected LS variants, giving builders flexibility in induction strategy. Cast aluminum construction provides excellent thermal characteristics and durability under sustained high-RPM operation, while the compact footprint—just 15.25 inches wide and 20.5 inches in height—clears most aftermarket hood designs without clearance issues. This intelligent design keeps intake charge temperatures lower and supports consistent performance across varied ambient conditions.
LS engine swaps into vintage muscle cars, Camaros, Corvettes, and contemporary platforms benefit most from this manifold's space-saving architecture and proven flow characteristics. The kit fits LS1, LS2, and LS6 variants—accounting for displacement and cylinder head differences—making it a versatile choice for both naturally aspirated and supercharged applications. Installation pairs easily with stock LS valley covers and standard engine bay layouts, and the front-feed design eliminates complex fuel system modifications required by side-feed alternatives. At 29.15 lbs, the assembly maintains structural rigidity without adding excessive mass, contributing to improved weight distribution and response in performance vehicles.
