MSD Ignition Atomic Airforce Intake Manifold 27003

Upper - 103mm Throttle Body Bore - Polymer - Black w/Solid Black Logos

Performance, polymer intake manifold for GM LT1 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*. The intake bolts on and is supplied with new gaskets and hardware for a direct bolt-on package.
