Holley Modular Ultra Lo-Ram EFI Manifold LS1/2/6

Lo-Ram Manifold Kit - LS1/2/6-Black Finish

Overview
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 low height to aid the packaging of a plenum-mounted air-to-water intercooler in a top-entry configuration. The 300-620 plenum entry configuration is designed to allow the included Hi-Ram 105 mm plenum top to be fitted to a low-profile base intake manifold. The short runner, low-profile base intake manifold intended for forced induction applications was conceived to package with an air to water plenum mounted intercooler with a shorter overall height than possible with other existing intake manifolds. 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.

Lo-Ram Base Intake Manifold Plenum Top Mounting Flange Height - 5.17" Total Height: Plenum Configuration w/105mm Long. Mount EFI Plenum Top - 9.07" (without an intercooler installed) Plenum Configuration w/105mm Long. Mount EFI Plenum Top, w/an intercooler installed - 9.07"+ the intercooler thickness

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 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)
