Description

The FAST LSXr 102mm Intake Manifold (146102B) is a high-performance, fuel-injected intake manifold engineered for GM rectangular port LS3, L76, L92, and L99 engines. Developed through a collaboration between FAST engineers and RHS airflow specialists, this manifold delivers measurable power gains over the factory unit. Constructed from an advanced polymer composite, the LSXr offers reduced weight, greater structural strength, and superior heat dissipation compared to traditional aluminum intakes. Testing on a stock LS3 engine demonstrated gains of 14+ horsepower and 11+ ft-lbs of torque at the flywheel.
