GM LS 102mm Aluminum Intake Manifold - Clear Anodized

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.

Fabricated Aluminum Intake Manifold Technology
The Top Street Performance LS 102mm Intake Manifold is engineered for enthusiasts seeking increased airflow and improved engine performance. Manufactured from TIG-welded T-6061 aluminum, this fabricated intake manifold utilizes a large center plenum, short runners, and velocity stack runner entries to help maximize airflow throughout the operating range. Individual port O-rings provide a secure seal while the clear anodized finish offers durability and corrosion resistance.

Performance Benefits
