Performance Benefits
The dual-plane runner design promotes efficient airflow distribution, helping improve throttle response, torque production, and overall engine performance. Its design makes it an ideal choice for cruising, weekend performance vehicles, street rods, hot rods, and classic muscle car LS swap projects.

What engines is this intake manifold compatible with?
This intake manifold is designed for GM LS Gen III cathedral port applications, including 5.7L/346ci.

Will this intake fit LS cathedral port engines like 4.8L, 5.3L, 5.7L, or 6.0L combinations?
Yes, this intake is designed for LS cathedral port combinations commonly used in Gen III-based applications.

What type of carburetor does this intake support?
This intake uses a 4150 square bore carburetor flange and is designed for carbureted applications.

What RPM range is this intake designed for?
This intake is designed to operate from 1,500-6,500 RPM, making it suited for broad street and street/strip performance.

How does a dual-plane intake help performance?
A dual-plane intake helps improve low-end torque and mid-range drivability by maintaining strong air velocity through the operating range.

Is this intake better for street or race use?
This intake is best suited for street performance and mild street/strip applications where broad power and drivability matter.

What type of intake manifold is this?
This is a dual plane, for cathedral 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 5.070 in., rear height of 6.140 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.

Is this a direct bolt-on carbureted intake manifold?
In most cases, this intake is designed as a direct-fit carbureted manifold for compatible LS applications, though proper gaskets, fuel system setup, and supporting components are still recommended.

What else should I know before installation?
As with any performance intake upgrade, proper fuel, ignition, and tuning support are important to get the best results from the manifold.

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.
