Description

Performance Intake Upgrade. The Holley Sideways and Inline Mount GM LS3/L92 Modular Carbureted Hi-Ram Intake Manifold offers a cost-effective solution for high-performance builds using LS3 and L92 engines. It improves air flow and engine breathing for both naturally aspirated and forced induction setups, delivering enhanced power at high RPM ranges. This manifold is suited for a variety of applications including muscle cars, drag racing, off-road, and marine uses.

Construction and Appearance. Built from durable cast aluminum, this intake manifold features a natural finish that highlights its rugged race-bred design. The tapered runner cross-section and precise casting provide an efficient flow path, while the molded O-ring sealing surfaces ensure a reliable and leak-free fitment.

Installation. Installation requires moderate mechanical skill, especially when converting from EFI to a carbureted fuel system. No major engine modifications or drilling are necessary. The removable top/lid provides easy access to the manifold’s interior for maintenance or tuning.

Warranty. This product carries a manufacturer’s limited 90 day warranty, offering peace of mind with your performance upgrade.

Application. This intake manifold is designed for engines using LS3/L92 style rectangular port cylinder heads with carbureted fuel systems. It is intended for racing or off-road use. While it may fit certain 6.2L engines like those found in 2008 Tahoe models, vehicle-specific fitment depends on several factors including hood clearance and fuel system configuration. Professional installation and fitment confirmation are recommended.
