The Holley LS1/2/6 Lo-Ram intake manifold kits are designed for GM LS Gen III and IV engines equipped with GM LS1/2/6 (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 the 105 mm throttle body part number 112-581 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 300-621 Lo-Ram front-feed plenum entry was configured to provide a very low profile modular intake manifold suitable for turbocharged or centrifugally supercharged engines. The 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. Features: Designed for GM LS Gen III and IV engines equipped with GM LS1/2/6 (cathedral port) cylinder heads Designed for forced induction (supercharged or turbocharged) engine applications with peak power at 7000-8000 rpm depending on the application. 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 Modular design allowing the use of front-feed plenum entry Intake design facilitates custom inlet duct and throttle body placement Low height to fit under a stock or mildly modified hood in the front-feed configuration Front entry plenum flange allows design & fabrication of special throttle body adapters or inlet ducts for custom installations Clears 4th Gen Camaro and C5 Corvette cowls and hoods without modification High volume fuel rails and mounting hardware included with -16 o-ring ports (8 AN)
