Description
High-Performance Intake Manifold. The Holley Sideways and Inline Mount GM LS3/L92 Modular Carbureted Hi-Ram Intake Manifold delivers optimized airflow for naturally aspirated and forced induction engines. It supports engine breathing at high RPMs, designed for performance builds targeting maximum power output in the 6.0 to 7.0+ liter range.
Construction and Appearance. Crafted from cast aluminum, this intake manifold offers durability and heat resistance with a lightweight design. The natural finish features a rugged, race-inspired style suitable for various high-performance applications.
Installation. The manifold is designed to bolt directly onto LS3/L92 rectangle-port engines using the standard mounting flange without requiring drilling. Due to its tall Hi-Ram design and dual 4150 carburetor flange, careful consideration of vehicle-specific hood clearance and fuel/induction setup is necessary.
Warranty. This intake manifold includes a manufacturer’s limited 90-day warranty covering defects in materials and workmanship.
Application. Specifically engineered for GM LS3/L92 rectangle-port engines in the 6.0 to 7.0+ liter range and intended for racing use only vehicles. Verify fitment and clearance in your application prior to installation, as this manifold is not legal for use on street-driven, emissions-controlled vehicles.
