The true brilliance of the MSD Atomic AirForce Intake Manifold lies in its thoughtful construction. Unlike traditional cast aluminum manifolds, the Atomic AirForce utilizes a robust, lightweight polymer molded 2-piece design. This advanced polymer material offers several key advantages:

• Thermal Efficiency: Polymer naturally resists heat soak far better than aluminum, keeping the incoming air cooler. Cooler air is denser air, which means more oxygen for combustion and, ultimately, more power.
• Lightweight Durability: The polymer construction contributes to a lighter overall engine weight, improving the power-to-weight ratio, while still offering exceptional strength and durability to withstand the rigors of high-performance applications.
• Optimized Manufacturing: The molding process allows for intricate internal designs that are difficult or impossible to achieve with traditional casting methods, leading to superior airflow characteristics.

The 2-piece design itself is a significant advantage. It allows for incredibly easy access to the runners, which is invaluable for enthusiasts who wish to further port or modify the manifold to perfectly match their specific engine build and flow requirements. This level of accessibility highlights MSD's commitment to tunability and customization, empowering owners to fine-tune their intake system for absolute peak performance.

Key Features and Unrivaled Benefits

Every aspect of the MSD Atomic AirForce Intake Manifold has been engineered with performance in mind. Let's delve into the specific features that make this manifold a standout choice for your LS7:

1. Superior Airflow and Distribution

This is where the Atomic AirForce truly shines. Its design directly addresses common airflow limitations found in stock manifolds:

• Bell-Mouthed Runner Entrances: A signature feature, these specially designed entrances maximize airflow into the runners. By mimicking the smooth, unobstructed entry of a trumpet bell, they significantly reduce turbulence and improve the volumetric efficiency of each cylinder.
• Minimized Shrouding: The internal geometry is meticulously optimized to minimize any shrouding or obstruction of airflow as it moves from the plenum into the individual runners. This ensures an unobstructed flow path, even over opposing runners.
• Optimized Plenum Volume: The plenum, the central chamber that distributes air, is precisely designed to optimize volume without compromising flow. This careful balance ensures that air is readily available to all runners, providing consistent cylinder-to-cylinder distribution, which is critical for smooth engine operation and maximum power output.

2. Enhanced Throttle Body Compatibility

The MSD Atomic AirForce Intake Manifold offers excellent flexibility for your throttle body setup. It is designed to accept an OEM throttle body, making it a straightforward bolt-on upgrade for many.

3. Flexible Fuel System Integration

Whether you're running a completely stock fuel system or have upgraded to high-flow aftermarket components, the Atomic AirForce is designed for seamless integration. This versatility ensures that your fuel delivery system can keep up with the increased airflow and potential power demands that this manifold unlocks.

4. Advanced Polymer Construction for Performance Advantage

As mentioned, the high-quality polymer material is not just about weight savings. Its ability to dissipate heat much faster than aluminum ensures that the air entering your engine remains as cool and dense as possible. This directly translates to more consistent power, especially during extended periods of spirited driving or track use, where heat soak can be a significant enemy of performance.

Why Upgrade Your LS7 Intake Manifold with MSD Atomic AirForce?

The GM LS7 engine, found in iconic vehicles like the C6 Corvette Z06, is a marvel of engineering. However, even the best factory designs often leave room for improvement, especially when performance is the ultimate goal. A factory intake manifold must balance many factors, including cost, noise reduction, and packaging constraints, which can compromise peak performance.
