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.

Product Features:

• Available with Red, Black or Silver logos
• 103mm Throttle Bore For Greater Air Flow
• Direct Flow Path Runner Design
• Allows For The Use Of Stock Fuel Rails

The Modular Mid-Rise intake utilizes the popular Holley LS1/LS2/LS6 cathedral port Mid-Rise 2 x 4 intake Manifold along with a purpose built plenum base Adapter and a Holley 92MM EFI plenum top which converts it into a Mid-Rise EFI intake manifold. With a max overall height of only 10.44in., the Mid-Rise Manifold is an excellent choice for street and performance street/strip applications with a powerband from 1,500-6,500 RPM and limited hood clearance. It’s perfect for a blow-thru or turbocharged application. Being part of the Holley modular intake line means that this intake is not only available as a complete kit with intake, adapter, 92MM top and fuel rails, but all parts can also be purchased separately for a custom intake build. The plenum Adapter (PN 300-231) will accept all of the popular Holley Hi-Ram plenum tops as a foundation for custom induction systems.
