102mm Aluminum Intake Manifold

The Top Street Performance GM LS 102mm Aluminum Intake Manifold is a black, fabricated aluminum component engineered to upgrade LS-powered builds. Designed specifically for GM LS cathedral-port engines, this manifold aims to increase airflow capacity, enhance throttle response, and improve high-RPM performance for applications such as street performance, drag racing, LS swaps, and boosted engines. Featuring a substantial 102mm throttle body opening, this intake manifold is built to maximize airflow for high-output engine combinations. Its fabricated aluminum construction incorporates a large center plenum, short runners, and velocity stack runner entries, which contribute to improved airflow efficiency and cylinder distribution compared to stock manifolds. The TIG-welded T-6061 aluminum ensures exceptional durability and a lightweight design. Individual port O-rings are included to guarantee a reliable seal at each intake runner and throttle body opening. The black finish provides corrosion resistance and a performance-oriented aesthetic. This manifold is suitable for various LS engine displacements, including 4.8L, 5.3L, 5.7L, and 6.0L applications, and is designed for electronic fuel injection systems. It is also well-suited for naturally aspirated and boosted applications. However, it is crucial to note that this intake manifold is not compatible with rectangle-port LS cylinder heads. Buyers must verify hood clearance, fuel system compatibility, throttle body compatibility, and accessory clearance before installation. Additionally, this Top Street Performance product is designated for racing and off-road competition use only. It does not comply with federal, state, or local emissions regulations and is not legal for use on public roads or emissions-controlled vehicles. The buyer assumes full responsibility for legal use and installation.
