This intake manifold is engineered for GM LS Series applications and helps support consistent airflow, clean fuel distribution, and dependable street performance operation across a wide range of compatible builds.

Airflow & Performance Design
The intake runner and plenum design help support balanced airflow delivery between cylinders while maintaining stable throttle response and dependable street-driven performance.

Construction & Engine-Bay Fitment
The manifold construction to support long-term durability, heat management, and a clean installed appearance in demanding engine-bay environments.

Installation Considerations
Proper installation requires confirming cylinder head compatibility, intake gasket alignment, carburetor or throttle-body configuration, distributor clearance, and hood clearance before final assembly.

System Matching
Verify fuel system compatibility, throttle linkage setup, vacuum routing, sensor provisions, and accessory clearance before installation. This intake manifold is intended for properly matched engine combinations.

What engines is this intake manifold compatible with?
This intake manifold is designed for GM LS Gen III cathedral port applications, including 4.8L/293ci, 5.3L/325ci, 5.7L/346ci, 6.0L/364ci.

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 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, low-rise design, 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 8.286 in., center height of 8.750 in., rear height of 7.132 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 3.000 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 natural finish affect performance?
No, the natural finish does not change performance—it offers a raw performance look that works well on race- and street-oriented builds.

How should I maintain the natural finish?
Routine cleaning and occasional metal-safe detailing will help keep the natural finish looking its best over time.
