Q&A

What engines is this intake manifold compatible with?
This intake manifold is designed for GM LS Gen IV 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 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 2,500-7,000 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, 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 5.417 in., center height of 5.417 in., rear height of 5.417 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 satin finish affect performance?
No, the satin finish is cosmetic and does not change performance—it provides a clean, understated appearance.


Does the satin finish require much maintenance?
The satin finish is relatively easy to maintain and usually only needs routine cleaning to keep it looking good.
