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

Answered by the admin
No, this is an LS7 specific manifold. LS3 and LS7 manifolds are not interchangeable. If you are looking for the best performing LS3 manifold for most applications check our LS3 Ported and Rodmodded Manifold. If you want to read our LS3 Manifold Comparison Testing - check it out HERE.
