GM LS1/LS2 EFI Intake Manifold - Satin

The Professional Products GM LS1/LS2 EFI Intake Manifold in satin finish is a precision-engineered aluminum induction system designed for General Motors LS-series engine platforms. This multi-port manifold features a throttle body flange configuration optimized for modern EFI fuel injection systems, delivering improved air distribution and intake velocity across the engine's cylinder banks. The satin aluminum finish provides both aesthetic refinement and corrosion resistance, making it suitable for street, strip, and performance applications where reliability meets visual appeal.

Built to OEM specifications for LS1 and LS2 variants, this intake manifold accommodates factory electronic fuel injection systems without modification. The multi-port design ensures balanced plenum volume and intake runner geometry, critical factors in achieving consistent fuel atomization and combustion efficiency across the entire RPM band. At 32.75 pounds, the aluminum construction reduces inertial mass compared to cast-iron alternatives, which translates to faster spool response in turbocharged applications and improved transient throttle response in naturally aspirated builds. The manifold accepts standard LS throttle bodies and integrates seamlessly with OEM or aftermarket fuel rail configurations.

This component serves engine builders, performance shops, and LS-platform enthusiasts executing restorations, upgrades, or complete drivetrain swaps. Whether converting a carbureted engine to fuel injection or replacing damaged OEM intake systems, this manifold provides proven fitment and flow characteristics. The satin finish resists thermal oxidation better than polished alternatives while maintaining a professional appearance under the hood. Installation requires standard hand tools and compatibility with existing LS block and cylinder head configurations—no special adapters or extensive modifications needed for direct bolt-on application.
