Description
Upgrade your LS-powered build with the Top Street Performance GM LS Gen IV Rectangle Port Carbon Fiber Low-Rise Intake Manifold. Engineered for LS3, L92, L99, and other GM Gen IV rectangle-port LS engines, this LS carbon fiber intake manifold combines lightweight construction, exceptional airflow capability, and modern performance styling for street performance, track builds, restomods, and LS swap applications.
Constructed from premium carbon fiber with precision-machined aluminum flanges, this LS rectangle port intake manifold helps reduce weight while minimizing heat soak compared to traditional cast aluminum intake manifolds. The low-rise design provides excellent hood clearance for many vehicle combinations while still delivering the airflow needed for high-performance EFI applications.
Designed for serious street and performance use, this LS3 intake manifold features a large 102.2mm throttle body opening, removable top design, integrated fuel rail provisions, and compatibility with modern electronic fuel injection systems. The modular construction simplifies installation, tuning, and future upgrades while maintaining a clean, professional appearance under the hood.
Whether you're upgrading an LS3 intake manifold, building a 6.0L rectangle-port LS combination, assembling a high-horsepower 6.2L engine, or completing a custom LS swap, this carbon fiber intake manifold delivers the airflow, weight savings, throttle response, and performance potential enthusiasts expect from a premium LS intake upgrade.
Carbon Fiber Intake Manifold Technology
The Top Street Performance LS Gen IV Rectangle Port Carbon Fiber Intake Manifold is engineered for builders who demand maximum airflow, reduced weight, and premium engine bay appearance. Constructed from lightweight carbon fiber with precision-machined aluminum flanges, this intake manifold helps reduce heat soak while providing the durability required for demanding street and performance applications.
Performance Benefits
The low-rise runner design provides an excellent balance of airflow capability and vehicle clearance, making it ideal for LS swaps, restomods, street performance builds, and track applications. The carbon fiber construction helps reduce weight while supporting high-horsepower EFI combinations that require efficient airflow and consistent performance.
