Speedmaster Chevy GM LS3 Dual Plane 4150 MID-AIR™ MidRise Aluminum Intake Manifold Satin

The Speedmaster Chevy GM LS3 Dual Plane 4150 MID-AIR™ MidRise Aluminum Intake Manifold is a high-performance intake solution engineered for LS3 engine platforms. This aluminum manifold features a dual-plane design that optimizes air distribution and improves engine efficiency across the RPM band, making it ideal for street and performance applications where consistent torque delivery is critical.

Manufactured from lightweight aluminum with a professional satin finish, this 4150-flange intake manifold integrates the MID-AIR™ mid-rise configuration to maximize clearance and fitment in tight engine bays while maintaining optimal volumetric efficiency. The dual-plane layout separates cylinder groups for improved low- to mid-range power characteristics, offering enthusiasts a refined balance between street driveability and performance gains. Compatible with LS3-based engines and systems configured for this intake flange size, this manifold serves as a direct bolt-on replacement for OEM or upgrading traditional single-plane configurations.

Key Features & Benefits

• Dual Plane Design: Optimized cylinder group separation improves torque distribution and throttle response across a broad RPM range.
