Designed for high-performance EFI applications, this LS3 hi-rise intake manifold features a large throttle body opening, removable top design, integrated fuel rail provisions, and compatibility with modern electronic fuel injection systems. The modular construction simplifies installation, tuning, maintenance, and future upgrades while providing a clean, professional appearance.

Whether you're upgrading an LS3 intake manifold, building a boosted 6.0L combination, maximizing airflow on a 6.2L LS build, or assembling a dedicated race engine, this carbon fiber LS intake manifold delivers the airflow capacity, weight savings, and horsepower potential serious LS enthusiasts demand.

Carbon Fiber Intake Manifold Technology
The Top Street Performance LS Gen IV Rectangle Port Carbon Fiber Hi-Rise Intake Manifold is engineered for maximum airflow, reduced weight, and premium engine bay appearance. Constructed from lightweight carbon fiber with CNC-machined aluminum flanges, this intake manifold helps reduce heat soak while providing the strength required for demanding street and racing applications. The removable top design allows easy access for tuning, maintenance, and future upgrades.

High-Horsepower Performance Benefits
