MSD - Atomic AirForce Intake Manifold (LS1, LS2, LS6)

When you’re serious about power for your LS2 engine, call in the AirForce! The all-new MSD Atomic AirForce intake manifold delivers improved airflow and distribution to improve the performance of stock and modified engines. The unique bell-mouthed runner entrances maximize airflow and minimize shrouding - all while optimizing the available plenum volume for an unobstructed flow path over opposing runners. The polymer molded 2-piece design allows for easy access to the runners for porting. Atomic AirForce accepts an OEM or 103mm throttle body as well as stock or aftermarket fuel rails* including MSD’s Atomic LS EFI system. The intake bolts on and is supplied with new gaskets and hardware for a direct bolt-on package. Product Features: Polymer material resists heat soak and minimizes weight. 103mm Throttle bore allows the use of large throttle bodies for greater air flow. Direct flow path runner design promotes maximum airflow. Allows for the use of stock fuel rails, aftermarket rails including the Atomic LS EFI. The two-piece manifold design provide convenient access to the runners for porting. Designed using Computational Fluid Dynamic Modeling to create optimal plenum volume and efficient air flow paths. Patent Pending CARB Pending. MSD Part Number: 2702 ***Installation Notes for LS1/LS6 Engines*** The Atomic AirForce manifold uses a 4-bolt throttle body mount. To use the OEM LS1/6 3-bolt throttle body, MSD offers adapter PN 2709. OEM fuel rails cannot be used on the LS1/6 Atomic AirForce Manifold. MSD recommends using fuel rails designed for LS2/3 applications.
