Holley Modular Lo-Ram 105mm EFI Intake Manifold for LS1, LS2 and LS6 engines.

These Holley LS1/2/6 Lo-Ram intake manifold kits (300-621) 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 105mm throttle body improves flow.

Features and 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 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
· High volume fuel rails and mounting hardware included with ¾”-16 o-ring ports (8 AN)

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 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.
