Performance Polymer Intake Manifold for GM LS7 Engines

The 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.*Note: Use of aftermarket rails may require the use of customer-supplied spacers and hardware.
