The MSD Atomic AirForce intake manifold improves airflow and distribution to boost the performance of stock and modified GM LS1, LS2, and LS6 engines. Bell-mouthed runner entrances maximize airflow and minimize shrouding while optimizing plenum volume for an unobstructed flow path over opposing runners. The molded 2-piece polymer design allows easy access to the runners for porting, and it accepts an OEM or 103mm throttle body along with stock or aftermarket fuel rails, including MSD's Atomic LS EFI system.
