Description

High-Performance Intake Manifold. The Holley Hi-Ram EFI Intake Manifold with 92mm Throttle Body Mount in black is engineered to enhance engine power and efficiency for GM LS family engines equipped with cathedral-port LS1, LS2, and LS6 cylinder heads. It provides superior airflow and pressure management, making it suitable for naturally aspirated or forced induction applications within a 3500 to 8000+ RPM range. This manifold is designed for racing use vehicles only and is not emissions legal for street use.

Construction and Features. Made from durable cast aluminum with a black finish, this modular manifold accepts a wide range of carbureted and EFI tops. It includes EFI fuel rails machined for high-flow -8AN O-ring fittings to ensure optimal fuel delivery. The manifold features a large plenum and tapered runners with a cathedral port shape to maximize performance. Vacuum ports are included; fuel injectors and throttle body are not included, though a 92mm throttle body bore and gasket are provided.

Installation. This manifold is designed as a high-performance aftermarket component for specific LS cathedral port engines and should be installed by an experienced mechanic familiar with race-oriented intake systems. It is not intended as a direct replacement for stock manifolds, given its single plane Hi-Ram design and substantial overall height of 12.32 inches from the lifter valley cover flange.

Warranty. Manufacturer's limited 90-day warranty applies.

Application. Specifically fits the 1997-2004 Corvette C5 and the 2005-2007 6.0L Corvette C6, providing an effective upgrade for these performance vehicles.
