Brand New Holley Modular Lo-Ram EFI Manifold Kit, Front-Feed Plenum, Silver Finish, Compatible with LS1, LS2 & LS 6 Gen III & IV Engines (Part #300-621)

The Holley LS1/2/6 Lo-Ram intake manifold kits are designed for GM LS Gen III & IV engines equipped with GM LS1/2/6 (cathedral port) cylinder heads. These intake manifolds will work with OE or aftermarket cylinder heads. These manifolds are designed for forced induction (supercharged or turbocharged) engine applications & 105mm throttle body part #112-581 or similar models.

The base intake manifold is designed with low height to aid the packaging of a plenum mounted air-to-water intercooler in a top-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 2 sets of brackets: A set for long (usually standard length) fuel injectors & set for short (such as Pico, or LS7) fuel injectors.
