Upgrade your LS-powered build with the Top Street Performance GM LS 102mm Aluminum Intake Manifold. Designed for GM LS cathedral-port engines, this fabricated aluminum intake manifold delivers increased airflow capacity, improved throttle response, and enhanced high-RPM performance for street performance, drag racing, LS swap, and boosted engine applications.

Engineered around a large 102mm throttle body opening, this LS intake manifold is designed to maximize airflow for high-output engine combinations. The fabricated aluminum construction features a large center plenum, short runners, and velocity stack runner entries that help improve airflow efficiency and cylinder distribution compared to many stock-style intake manifolds.

Constructed from TIG-welded T-6061 aluminum, this LS fabricated intake manifold provides exceptional durability while maintaining a lightweight design. Individual port O-rings help ensure a reliable seal at each intake runner and throttle body opening, while the clear anodized finish provides corrosion resistance and a clean performance appearance.

Whether you're upgrading a 5.3 LS intake manifold, building a high-performance 6.0 LS combination, completing a turbocharged LS project, or looking for a 102mm intake manifold capable of supporting serious horsepower, this LS aluminum intake manifold delivers the airflow and performance potential demanded by performance enthusiasts.
