The LS1/LS2/LS6 Single Plane Mid-Rise EFI Intake Manifold (Holley 300-137) is designed for high-performance applications, offering a balance between low-end torque and high-RPM power. It features a single-plane design, which enhances airflow distribution and increases top-end horsepower, making it ideal for naturally aspirated and forced induction setups. The mid-rise design helps maintain adequate hood clearance while still supporting increased airflow compared to stock intake manifolds.

Features
