Speedmaster LS1 LS2 LS6 Dual Plane Fuel Injected Intake Manifold, Satin Finish

The Speedmaster LS1 LS2 LS6 dual plane fuel injected intake manifold (MPN 1-148-053-01) is a performance-oriented engine component designed to optimize air and fuel distribution for Chevrolet LS-series engines. This satin-finish manifold is engineered for 2x4-barrel fuel injection setups, providing efficient volumetric flow and combustion characteristics across the intake ports.

This intake manifold is ideal for engine builds and performance modifications on LS1, LS2, and LS6 platforms. The dual plane design promotes low and mid-range torque development, making it suitable for street performance applications, drag racing, and naturally aspirated engine builds where consistent fuel delivery and optimal manifold geometry are priorities. The satin finish provides both a refined appearance and protection against thermal cycling and corrosion.
