FAST 146104B LSXR 102mm Intake Manifold LS3 L92 Rectangle Port Black

The FAST 146104B LSXR 102mm intake manifold is a high-performance race-spec intake designed specifically for LS3 and L92 rectangle port applications. Featuring an oversized 102mm throttle body opening, this manifold is engineered to maximize airflow and power output on modified engines with aggressive camshafts and higher RPM operation.

Key Features:

• 102mm throttle body flange for maximum airflow capacity
• Rectangle port design optimized for LS3/L92 cathedral port heads
• Advanced polymer composite construction in black finish
• Lighter weight than aluminum alternatives while maintaining superior strength
• Improved heat dissipation characteristics reduce intake air temperatures
• Direct bolt-on fitment for LS3 and L92 engines
• Race-proven design for street/strip and competition applications

The LSXR's polymer construction offers significant advantages over traditional aluminum manifolds, including reduced weight for improved weight distribution, superior thermal properties that help keep intake temperatures lower, and exceptional durability. The 102mm opening provides the airflow necessary to support high-horsepower builds while the optimized runner design ensures excellent distribution across all cylinders.
