HO300-621 - HOLLEY EFI INTAKE MANIFOLD MODULAR ULTRA LO-RAM FITS GM LS1/2/6

Holley Ultra Lo-Ram Manifold Kit - LS1/2/6Notes: 0.810 in. collar diameter.

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. 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 300-621 Lo-Ram 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 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 ¾”-16 O-ring ports (8 AN)
