FAST 146051-1 Replacement Left Hand Runner for LSXR 102mm Intake Manifold

The FAST 146051-1 is a replacement left-hand (LH) intake runner designed specifically for FAST LSXR 102mm intake manifolds on GM LS3, L99, L76, and L92 rectangle port engines. This individual replacement runner is part of FAST's innovative modular intake manifold system that allows for easy disassembly, maintenance, and customization.

Key Features:

• Direct replacement left-hand runner for FAST LSXR 102mm intake manifolds
• Constructed from advanced polymer material for superior heat dissipation and strength
• Modular design allows individual runner replacement without replacing entire manifold
• Designed for LS3, L99, L76, and L92 rectangle port applications
• Compatible with standard, High HP, and Race LSXR manifold configurations
• Includes necessary O-rings and mounting hardware

The LSXR's three-piece modular design revolutionized LS intake manifolds by enabling users to remove and replace individual runners for porting modifications or replacement due to damage. This replacement runner maintains the same advanced polymer construction as the original LSXR components, offering lighter weight and improved thermal characteristics compared to aluminum alternatives.
