Holley EFI Modular Lo-Ram EFI Manifold for Gen III or IV LS engines with LS1, LS2, or LS6 heads (300-621BK)
Features/Benefits:
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.
Modular design allowing the use of frontfeed 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
(4th Gen 1998-2002 Camaro/Firebird) and (C5) 1997-2004 Corvette cowls and hoods without modification
High volume fuel rails and mounting hardware included with ¾”-16 o-ring ports (8 AN)
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 manifold has been designed for forced induction (supercharged or turbocharged) engines where the short runner length and higher engine RPM applications are an ideal fit. The intake is designed to work with the Holley EFI 105mm throttle body Part # 112-581 (sold separately). 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.
