      Description

      High-Performance Intake. The Holley GM LS3/L92 Hi-Ram EFI Lower Intake Manifold Base is engineered to maximize airflow and improve engine performance on naturally aspirated and forced induction setups. This base manifold enhances throttle response and overall power delivery, particularly suited for high-RPM applications in muscle cars, drag racing, and off-road vehicles.

      Construction and Appearance. Constructed from durable cast aluminum, this intake manifold features a natural finish that showcases its robust build quality. Designed with a single-plane configuration, it includes tapered, as-cast runners and a gasket-sealed plenum top for reliable sealing and efficient air distribution.

      Installation. Installation is straightforward and does not require drilling or major modifications; however, clearance and compatibility with vehicle-specific accessories, fuel systems, and throttle bodies should be considered. The removable top facilitates easier maintenance and installation.

      Warranty. This manifold comes with a manufacturer’s limited 90-day warranty covering defects in materials and workmanship.

      Application. Designed to fit GM LS-family engines equipped with LS3/L92-style rectangle port cylinder heads. Compatibility should be verified for specific vehicle applications and any required modifications.
