GM LS Hi-Ram Intake Sys. - 105mm EFI Throttle Bdy

The Holley GM LS Hi-Ram Intake System with 105mm EFI Throttle Body is designed for builders aiming for maximum airflow and responsive throttle control on LS-based powerplants. This single-plane intake manifold is ideal for street and strip enthusiasts who demand high-RPM scavenging characteristics, especially in boosted performance or naturally aspirated builds that require peak breathing efficiency.

Engineered specifically for GM LS engines, this system enhances intake dynamics by feeding all eight cylinders from a common plenum. This design supports aggressive cam profiles and high-load operation without fuel distribution inconsistencies. The 105mm EFI throttle body ensures precise electronic control with minimal restriction, which is crucial for tuning and drivability across idle-to-redline transitions.

The Holley Hi-Ram design optimizes runner length and cross-sectional area for improved cylinder charging, reducing reversion and enhancing scavenging efficiency at elevated RPMs. This intake system is compatible with LS1, LS2, LS3, LSx, and similar variants, making it an excellent choice for hot rods, restomod Camaros and Corvettes, and purpose-built race cars where enhanced airflow translates directly to horsepower gains and improved engine response.
