Description

Premium EFI Intake. The Holley GM LS3/L92 Single Plane EFI Intake Manifold enhances engine breathing by optimizing airflow to GM LS Gen III engines equipped with LS3/L92 style rectangular port cylinder heads. Designed to improve torque and horsepower within the 2500-7000 RPM range, it supports applications including centrifugal superchargers, turbochargers, and mild nitrous support.
