Description

Hi-Ram Lower Intake Manifold; EFI Base Only; Incl. Fuel Rails; Cast Aluminum; For Use w/LS1/LS2/LS6 Cathedral Port Heads; Black;

The Holley GM LS1/LS2/LS6 Modular HiRam Intake Manifold is introduced as a cost effective alternative to fabricated sheetmetal for highperformance applications where induction system height is not limited. Coupling this HiRam intake with the high flowing LS1/LS2/LS6 style cylinder heads has outstanding potential for N/A and forced induction applications at a budgetminded cost. Aggressive, bold, racebred styling will make bad intentions clear for drag race, muscle car, marine, offroad, sandrails, pulling trucks, track, streetrod applications and more! The base is designed to be modular in configuration to accept a wide range of carbureted and EFI tops and to be attractive to builders and fabricators as the foundation for custom induction systems. Runner length and the tapered crosssection designed to perform well for a wide range of engine configurations. EFI fuel rails are machined for 8AN Oring Fittings with passages large enough to accommodate high fuel flows and dampen pressure pulsations in the fuel system and come standard with EFI HiRam kits.
