Description

Upgrade your LS-powered build with the Top Street Performance GM LS Rectangle Port V-Series Billet Aluminum Hi-Rise Intake Manifold. Designed for Chevrolet Small Block V8 Gen III (LS-Based) 6.2L / 376ci applications, this premium billet aluminum intake manifold delivers exceptional airflow capacity, modular serviceability, and race-inspired styling for high-performance street, drag racing, and competition builds.

Fresh off its award-winning appearance at the 2024 SEMA Show, the V-Series intake manifold was engineered to maximize airflow efficiency and support serious horsepower potential. The single-plane hi-rise design features increased plenum volume and optimized runner geometry to improve airflow at higher engine speeds, making it an excellent choice for naturally aspirated, turbocharged, and supercharged engine combinations.

Manufactured from precision-machined T-6061 billet aluminum, this LS intake manifold provides exceptional strength, durability, and premium appearance. The modular design simplifies installation, maintenance, and future upgrades, while the included custom V-Series fuel rails help create a clean, professional engine bay appearance.

Designed for electronic fuel injection applications, the manifold utilizes a stock LS3 throttle body bolt pattern, high-flow plenum design, EV1 injector provisions, and Gen IV 3-Bar MAP sensor compatibility.

Whether you're building a high-performance 6.2L LS street car, race vehicle, restomod, or LS swap project, this billet aluminum intake manifold delivers the airflow capacity, tuning flexibility, and performance potential demanded by serious LS enthusiasts.

Q&A

What engines is this intake manifold compatible with?
This intake manifold is designed for GM LS rectangle port applications, including 6.2L/376ci.


Will this intake fit LS rectangle port engines like a 6.2L LS application?
Yes, this intake is designed for LS rectangle port combinations, making it a strong fit for common Gen IV performance applications.


What fuel system is this intake designed for?
This intake is designed for EFI applications using multi-port fuel injection, making it a strong choice for performance LS builds.


What RPM range is this intake designed for?
This intake is designed to operate from 1,500-9,000 RPM, making it suited for higher-RPM performance use.


How does a single-plane intake help performance?
A single-plane intake is designed to support stronger high-RPM airflow, making it a good choice for aggressive performance combinations that want more top-end power.


Is this intake better for street or race use?
This intake is better suited for aggressive street, street/strip, and higher-RPM performance applications.


What type of intake manifold is this?
This is a single plane, billet aluminum, hi-rise design, for rectangle applications intake manifold built to improve airflow and support performance LS combinations.


Will this intake clear a stock hood?
It features a performance-oriented intake profile, with a front height of 10.086 in., center height of 10.550 in., rear height of 8.933 in., so hood clearance should always be checked against your specific vehicle combination.


What material is this intake made from?
It is made from aluminum, which helps reduce weight while supporting strength and heat control for performance use.


What throttle body size or flange does this intake support?
This intake is designed around a 102.200 mm throttle body configuration, which supports increased airflow for EFI performance applications.


Does runner length affect how this intake performs?
Yes, this manifold uses a runner length of 4.800 in., which helps shape how the intake makes power across the RPM range.


Will this intake improve throttle response on my LS build?
Yes, this intake is designed to improve airflow and mixture distribution, which can help deliver stronger throttle response and more consistent power.


Is this a good upgrade from a stock intake?
Yes, this intake is a strong upgrade for compatible LS applications that need better airflow, stronger power potential, and improved performance over a stock-style manifold.


Does the black finish affect performance?
No, the black finish does not change the manifold's performance characteristics—it mainly changes appearance and gives the intake a more aggressive look.


Is the black finish durable for long-term use?
Yes, the black finish is designed for durability and corrosion resistance when properly maintained.
