Description
High-Performance Intake Manifold. The Holley LS7 EFI Hi-Ram Intake Manifold features a 92mm LS throttle body flange and includes fuel rails. It is engineered for naturally aspirated and forced induction LS7-style engines in the 6.0 to 7.0+ liter range, delivering maximum power at high RPMs between 7000 and 8000+. This intake manifold optimizes airflow and fuel delivery for enhanced engine performance, making it ideal for muscle car, drag race, and track enthusiasts.
Construction and Design. Crafted from cast aluminum with a natural finish, this manifold employs a single-plane Hi-Ram design and a modular base to accept a variety of EFI and carbureted top options. The tapered runner design improves airflow efficiency and power output across a broad range of engine configurations.
Installation. Designed to fit directly onto compatible LS7-style cylinder heads without requiring drilling, it provides flexible mounting options suitable for custom setups. Throttle body and fuel injectors are not included but mounting provisions and gaskets are supplied.
Warranty. Backed by a manufacturer’s limited 90-day warranty.
Application. Specifically fits 2014 to 2015 Camaro Z/28 models.
