FAST 146201 LSXR 102mm Raised Rectangle Port Intake Manifold Lower Shell

The FAST 146201 LSXR is a replacement lower shell designed for 102mm raised rectangle port intake manifold systems. Constructed from advanced composite polymer material, this lower shell delivers significant performance advantages over traditional aluminum components.

Key Features:

• 102mm throttle bore for maximum airflow capacity
• Raised rectangle port design optimized for high-flow cylinder heads
• Advanced polymer composite construction for reduced weight
• Superior heat dissipation properties compared to aluminum
• Increased structural strength and durability
• Black finish for a clean, professional appearance
• Direct replacement lower shell for FAST LSXR intake manifolds

The polymer material used in the LSXR lower shell stays cooler than aluminum, helping to reduce intake air temperatures for improved performance. The lightweight construction reduces overall engine weight while the enhanced strength characteristics ensure long-term reliability under demanding conditions. This component is specifically engineered for LS engines with raised rectangle port cylinder heads requiring maximum airflow potential.
