GM LS 102mm Aluminum Intake Manifold - Clear Anodized

• GM LS Series EFI intake uses 102 mm throttle-body sizing with Multi-port provisions for properly matched engine management.

• Runner length: 5.000 in. Plenum thickness: 4 mm. Designed to support consistent airflow distribution across the manifold.

• Injector provision: EV1. Verify injector height and fuel-line routing.

• Check hood clearance, accessory clearance, and wiring reach before installation.

For applications that need reliable intake airflow and clean engine-bay fitment, this intake manifold combines durable construction with application-focused runner and plenum design.

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 the engines listed in the fitment details?
Yes, this intake is built around the engine combinations shown in the fitment section for this product.

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

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

What is the advantage of a 102mm intake manifold?
A 102mm intake manifold is designed to support greater airflow, making it a strong option for higher-output LS combinations that need increased throttle body capacity.

Is this intake aimed more at performance builds than stock replacements?
Yes, this intake is intended more for performance-oriented builds that want increased airflow rather than a stock-style replacement.

What type of intake manifold is this?
This is a 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 6.750 in., center height of 6.750 in., rear height of 6.750 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 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 5.000 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 clear anodized finish affect performance?
No, the clear anodized finish does not change performance—it mainly adds surface protection and a clean performance appearance.

What are the benefits of a clear anodized finish?
A clear anodized finish helps add corrosion resistance and durability while maintaining a clean aluminum appearance.
