Description
High-Performance Induction System. The Holley GM LS3/L92 Modular EFI Hi-Ram Intake Manifold is engineered to optimize air delivery for naturally aspirated and forced induction engines in the 6.0 to 7.0+ liter range. It enhances engine breathing and performance at high RPM, making it ideal for drag racing, muscle cars, and various motorsports applications.
Construction and Appearance. This intake manifold features cast aluminum construction known for strength and lightweight properties, finished in a natural surface. The modular design allows compatibility with a broad selection of carbureted and EFI tops, delivering both versatility and durability without CNC porting. The manifold’s aggressive, race-focused styling complements high-performance builds.
Installation. Installation requires no drilling or modification of the engine block or cylinder heads. The manifold mounts using standard LS3 molded O-ring gaskets, providing a secure and proper seal for optimal performance. Experienced installers will find setup straightforward; however, some vehicle-specific adjustments to throttle body and fuel system plumbing may be necessary.
Warranty. This product is backed by the manufacturer’s limited 90-day warranty covering material and workmanship defects.
Application. Designed primarily for GM LS3/L92-style rectangle-port cylinder heads, this intake manifold fits engines from 6.0 to over 7.0 liters and supports both naturally aspirated and forced induction setups. It is compatible with vehicles such as the 2010-2015 Camaro SS and other applications using LS3/L92 cylinder heads.
