An LS intake manifold is a critical component of a high-performance engine's air intake system. It is an essential part of the system that provides the engine with the right amount of air and fuel mixture required to achieve maximum power and performance. LS intake manifolds are known for their impressive performance capabilities, which come from their unique design and engineering.
The LS intake manifold is typically made from lightweight, high-quality materials such as aluminum, which allows for a robust but lightweight construction. This design allows for a high degree of airflow and eliminates the restrictions common in traditional intake manifolds. Additionally, LS intake manifolds are often paired with advanced throttle bodies, fuel injectors, and other components, making them an essential part of any high-performance engine build.
The design of an LS intake manifold is also optimized for efficient fuel delivery, which reduces fuel consumption and improves fuel efficiency. The manifold's unique design features air channels, which reduce turbulence and ensure that air flows smoothly through the engine. This smooth flow of air results in an improvement in the engine's power output, better-accelerating performance, and an overall better driving experience.
In conclusion, an LS intake manifold is a crucial component in any high-performance engine build. With its superior design and advanced engineering, it can provide optimum airflow and fuel delivery to increase the engine's power and efficiency. If you're looking to take your engine performance to the next level, investing in an LS intake manifold can be a smart investment for achieving optimal power and performance.
How We Choose
While the stock intake manifold on your LS 4.8 or 5.3 will run fine if you are running a stock engine when you start adding things like a cam, headers, and a cold air intake you will find the original intake manifold is holding your LS engines performance below what is possible with a simple intake manifold swap. That said, GM does offer intake manifolds that will handle 500 horsepower or more so don't overlook GM as an option when you are ready to add new parts.
LS3 GM Genuine Parts 12580420 Intake Manifold Assembly
The LS3 intake manifold is widely recognized as one of the top factory options for LS engines. It is a high-performance aluminum block variant, with 426-436 horsepower and a displacement of 6.2 liters. The LS3 intake was used in various vehicles from 2008 to 2017, including the Corvette, Pontiac G8, Camaro, and Holden models.
This intake manifold ensures the even distribution of the combustion mixture or air (in the case of direct injection systems) to each intake port in the cylinder head, promoting optimal functionality. As a GM-recommended replacement part, it offers the same quality, reliability, and durability as the original factory component. Manufactured to GM OE specifications, it guarantees a precise fit, form, and function.

LS Intake Manifold FAQs
What intake manifold will make the most horsepower?
The intake manifold that will make the most horsepower depends on various factors, such as engine type, modifications, and application. However, in general, a larger manifold with a smooth runner design and larger air inlet can help increase horsepower without sacrificing low-RPM torque.
How does an LS intake manifold improve engine performance?
An LS intake manifold improves engine performance by allowing more air to flow into the cylinders at a higher velocity. This increased air volume and speed results in improved combustion and more power. Additionally, the smoother runner design and larger air inlet reduce airflow restrictions, resulting in better overall engine performance.
Is an LS intake manifold compatible with any LS engine?
While LS intake manifolds are specifically designed for engines equipped with Chevy, GMC, and Pontiac Cathedral Port heads (LS1/LS2/LS6), they can also fit other LS engine types with some modifications. However, it is always best to consult with a professional before making any modifications or upgrades.
What materials are LS intake manifolds commonly made of?
LS intake manifolds are typically made of either aluminum or plastic. Aluminum offers better heat dissipation and is ideal for high-performance applications, while plastic is lightweight and more affordable. Some aftermarket options also feature a combination of aluminum and plastic for the best of both worlds.
Conclusion
When adding performance parts to your LS engine you will eventually run into the need for more air and the only way to get that air is to change intake manifolds. There are so many factors in choosing the right intake manifold for your vehicle combination so you don't have problems when you hit the road, look at the cam, cold air intake, displacement, and headers. So go ahead and add the intake you need to your cart and get your LS road ready!
