Description
High-Performance Intake Manifold. The Holley Hi-Ram EFI Intake Manifold with 92mm Throttle Body Mount is engineered for high airflow on GM LS1/LS2/LS6 cathedral port engines. Designed for naturally aspirated and forced induction applications, it supports high-RPM operation in the 7000 to 8000+ RPM range, providing efficient air delivery for high-displacement, racing-use setups. This intake manifold is intended for competition use only and is not legal for street use in emissions-controlled vehicles.
Construction and Appearance. Made from durable cast aluminum with a natural finish to resist corrosion and heat, the intake manifold features a modular design that accepts a variety of carbureted and EFI tops. Integrated fuel rails are precision-machined for -8AN O-ring fittings, optimizing fuel flow and pressure stability.
Installation. Designed to fit LS1/LS2/LS6 cathedral port engine configurations, installation requires typical mechanical knowledge and should follow standard procedures for intake manifold replacement. Compatibility with OEM-style gaskets allows for proper sealing on approved engines.
Warranty. This product includes a manufacturer’s limited 90-day warranty covering construction and performance.
Application. Specifically designed to fit the 1997-2004 Corvette C5 and the 2005-2007 6.0L Corvette C6 engines. This fitment ensures compatibility with the OEM lifter valley and front engine mounting flanges without modifications, making it an ideal upgrade choice for these models.
