New at Summit Racing: MSD Atomic AirForce Intake Manifolds
Think an intake manifold swap isn’t worth the trouble on a GM LS or LT1 engine? MSD begs to differ. Lingenfelter Performance Engineering tested an MSD Atomic AirForce Intake Manifold against a ‘Brand X’ intake on one of its LS7-powered L28 Camaros. The AirForce manifold beat the other guy by 36 more rear-wheel horsepower and 16 lbs.-ft. of torque. That’s power you’ll definitely notice.
The Atomic AirForce manifold improves on the factory manifold design by increasing the overall plenum volume and removing airflow restrictions. The manifold also features straighter runners to optimize airflow. MSD engineers worked to equalize airflow between the top and bottom runners, which decreases air turbulence.
Other features include:
• Bell-mouthed runner entrance maximizes airflow and minimizes shrouding
• Two-piece design allows for easy access to the runners for porting
• Polymer construction resists heat soak and minimizes weight
• Works with any 103mm throttle body, both drive-by-wire and drive-by-cable
• Can be used with most stock or any aftermarket fuel rails
• Gaskets and bolts included
The MSD Atomic AirForce Intake Manifold also features three MAP sensor locations to help you position the sensor in a cramped engine bay. LS1/LS6 applications require the use of aftermarket LS2 style fuel rails and the MSD-2709 adapter to use OEM throttle body. If you have a cable-actvated throttle body, Summit Racing also carries MSD’s cable brackets for stock and aftermarket throttle cables.
Applications
• LS1/LS6
• LS2
• LS7
