Description
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 black 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 black finish offers durability and corrosion resistance.
Performance Benefits
Designed for performance-oriented LS engine combinations, the single-plane intake design and 102mm throttle body opening support increased airflow demand for naturally aspirated and boosted applications. The runner and plenum design help provide balanced airflow distribution while supporting strong throttle response and high-RPM performance. Designed for a 1,500-6,500 RPM operating range.

Q&A
What engines is this intake manifold designed for?
This intake manifold is designed for GM LS cathedral-port engines, including 4.8L, 5.3L, 5.7L, and 6.0L applications.
What is the advantage of a 102mm intake manifold?
A 102mm intake manifold is designed to support greater airflow, making it ideal for higher-output LS engine combinations that require increased throttle body capacity.
What RPM range is this intake manifold designed for?
This intake manifold is designed for performance applications operating from 1,500 to 6,500 RPM.
Will this intake manifold fit a 5.3 LS engine?
Yes. This intake manifold is compatible with supported 5.3L LS cathedral-port engine combinations.
Will this intake manifold fit a 6.0 LS engine?
Yes. This intake manifold is compatible with supported 6.0L LS cathedral-port engine combinations.
What are velocity stack runners?
Velocity stack runner entries help smooth airflow entering the intake runners, improving airflow efficiency at higher engine speeds.
Is this intake manifold designed for EFI applications?
Yes. This intake manifold is designed for multi-port electronic fuel injection systems.
Will this intake manifold support turbocharged or supercharged applications?
Yes. The high-flow plenum and runner design make this intake manifold well suited for naturally aspirated and boosted LS engine combinations.

Emissions Notice
This Top Street Performance (TSP) product is designed for racing and off-road competition use only. It is not legal for use on public roads or emissions-controlled vehicles and does not comply with federal, state, or local emissions regulations. The buyer assumes all responsibility for legal use and installation.
What is a Emissions-Controlled Vehicle?
"An emissions-controlled vehicle is any vehicle equipped with a factory-installed emissions control system designed to reduce air pollution. These systems include catalytic converters, oxygen sensors, EGR (Exhaust Gas Recirculation) valves, and diesel particulate filters (DPF). Most vehicles manufactured after 1975 are considered emissions-controlled and must comply with federal and state emissions laws when used on public roads."
