Description
High-Performance Intake. The Holley GM LS3/L92 Modular Mid-Rise EFI Intake Manifold with 92mm top is engineered to improve airflow and throttle response for GM LS Gen III and IV engines featuring LS3/L92 rectangular port cylinder heads. It is designed specifically for street and street/strip applications, supporting a broad powerband from 1500 to 6500 RPM, making it ideal for both naturally aspirated and forced induction setups, especially where limited hood clearance is a concern.

It features a natural finish that showcases its high-quality craftsmanship. The design incorporates a modular plenum base adapter, and the water-throttle body interface is CNC-machined to ensure precise fitment.
Installation. This manifold installs easily without the need for drilling or major modifications, offering a straightforward upgrade for most GM LS3/L92 engines. It includes all required gaskets and is compatible with fuel rail kits for a complete EFI system installation.
Warranty. The product is backed by a manufacturer’s limited 90-day warranty against defects in materials and workmanship.
Application. Compatible with 2007-2008 6.2L Sierra 1500 Denali models. Designed for engines requiring LS3/L92 rectangular port intake manifolds. Legal for use on uncontrolled (non-emissions controlled) vehicles only.
