GM LS Hi-Ram Intake Sys. - 92mm EFI Throttle Body

The Holley GM LS Hi-Ram Intake System with 92mm EFI Throttle Body is a high-flow intake manifold engineered for LS-series engine platforms, particularly Gen III/IV LS powerplants, requiring elevated air velocity and dual-plane port distribution. This system is ideal for performance enthusiasts and builders looking to enhance throttle response and mid-range torque delivery in their builds.

Constructed from cast aluminum in a natural finish, the Hi-Ram design employs a dual-plane configuration that optimizes air-fuel mixture distribution across all cylinders. The 92mm throttle body flange ensures compatibility with modern EFI systems, allowing seamless integration with both stand-alone and OEM engine control modules. This manifold is designed to resist thermal distortion and supports accurate fuel metering across the RPM band.

Engine builders, performance shops, and enthusiasts upgrading their LS powerplants for street or track applications will benefit from the Hi-Ram's multi-port layout, which prevents fuel pooling and enhances overall drivability. This intake system is particularly suited for naturally aspirated setups, ensuring consistent performance in various driving conditions.
