Description
High-Performance Intake Manifold. The Holley Hi-Ram EFI Intake Manifold with 92mm Throttle Body Mount is engineered to provide a modular and versatile induction solution for high-output GM LS1, LS2, and LS6 engines. It’s designed to optimize airflow for naturally aspirated and forced induction setups, helping maximize horsepower and torque in racing applications where superior airflow and tunability are desired.
Construction and Appearance. Constructed from cast aluminum, this intake manifold features a natural finish that highlights its durable and race-inspired design. The EFI fuel rails are machined for -8AN O-ring fittings, ensuring reliable fuel delivery while reducing pressure pulsations. The tapered runner cross-section supports optimal airflow across a wide RPM range.
Installation. Installation requires a moderate level of mechanical skill but does not require drilling or other major modifications. It mounts using standard LS3 style molded o-ring gaskets and includes all necessary gaskets for a proper seal, simplifying installation on compatible engines.
Warranty. This product comes with a manufacturer’s limited 90 day warranty covering defects in materials and workmanship.
Application. This intake manifold is compatible with GM LS1, LS2, and LS6 cathedral port cylinder heads and designed for engines between 6.0 to 7.0+ liters displacement. It is recommended primarily for performance and racing use, including forced induction applications. Specific vehicle fitment such as the 1998-2002 5.7L Camaro is not guaranteed and should be independently verified to ensure compatibility.
