GM LS Intake Manifold Dual Plane w/4150 Flange

The GM LS Intake Manifold Dual Plane w/4150 Flange is designed for automotive enthusiasts looking to enhance the performance of their GM LS-Series engines. This manifold serves as an ideal solution for those transitioning to setups that require a square bore mounting surface, such as carbureted or throttle body injection systems. Its dual plane design optimizes low-to-mid range torque, making it suitable for heavy-duty vehicle builds and tactical utility applications.

Constructed from high-strength cast aluminum with a natural finish, this Holley 300-130 intake manifold features a dual-plane runner configuration that effectively separates intake pulses. The 4150 flange design ensures compatibility with a wide range of standard square bore carburetors and EFI throttle bodies. This specific geometry enhances air-fuel mixture velocity, promoting consistent combustion across the entire RPM range.

Engineers and builders will appreciate the manifold's design, which is optimized for GM LS-Series engines, including LS1, LS2, and LS6 variants. It provides a seamless fit for cathedral port cylinder heads, ensuring reliable throttle response in demanding operational environments. This manifold is an essential component for anyone looking to maximize engine performance and efficiency.
