Kit, Int. Manifold, Ls1 Lo-Ram, Black

The Holley LS1/2/6 Ultra 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. Plenum top is machined for a standard "large" 6-1/8" x 3-1/8" burst panel. SFI approved burst panels, burst panel frame sets, and gaskets may be purchased from various manufacturers such as Allstar Performance or Specialty Fasteners

The Ultra 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. The 300-623 Ultra 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. Includes a burst panel flange in the lid
• Plenum top is machined for a standard “large” 6-1/8” x 3-1/8” burst panel. Burst panels, burst panel frame sets, and gaskets may be purchased from various manufacturers such as Allstar Performance or Specialty Fasteners
• 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
• Intake design facilitates custom inlet duct and throttle body placement
• Low height to fit under a stock or mildly modified hood.
• Front entry plenum flange allows design & fabrication of special throttle body adapters or inlet ducts for custom installations
• High volume fuel rails and mounting hardware included with ¾”-16 o-ring ports (8 AN)
• Available in satin or black finish
