GM LS Intake Manifold - LSXR 92mm Black

The FAST Electronics GM LS Intake Manifold LSXR 92mm Black is a precision-engineered air-delivery system designed for LS-platform engine builders and performance enthusiasts who demand maximum flow efficiency and reliability. This manifold is essential for forced-induction and high-output naturally aspirated LS builds, where intake velocity and runner design directly impact volumetric efficiency and power output. Whether you're tuning a street car, bracket racer, or weekend warrior, a quality intake manifold is crucial for extracting peak performance from your LS engine.

FAST's LSXR series features a 92mm bore that optimizes velocity across the RPM band while minimizing turbulence in the plenum chamber, which is critical for consistent fuel distribution and combustion. The black powder-coat finish resists corrosion and engine heat degradation, preserving structural integrity through thousands of heat cycles. This design balances thermal mass with weight savings, making it suitable for both street and track applications.

This intake manifold is ideal for LS1, LS2, LS3, LS6, and LS7 engine swaps, as well as standalone LS crate engine installations. Its robust construction ensures precise runner geometry under boost or high-RPM stress, maintaining fuel atomization and air-fuel ratio stability across all load conditions. Performance enthusiasts will appreciate the manifold's ability to enhance engine performance in a variety of applications.
