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.

FEATURES:

CARB Approved, 50 State Legal EO# D-722-3!
The two-piece manifold design provide convenient access to the runners for porting.
Allows for the use of stock fuel rails, aftermarket rails including the Atomic LS EFI.
Designed using Computational Fluid Dynamic Modeling to create optimal plenum volume and efficient air flow paths.

MSD 2702 Red Lettering Atomic LS Cathedral Port Intake Manifold for LS1/LS2/LS6 - MailOrder Tuner

The Holley Black GM LS1/LS2/LS6 Modular Hi–Ram Intake Manifold is introduced as a cost effective alternative to fabricated sheet–metal for high–performance applications where induction system height is not limited. Coupling this Hi–Ram intake with the high flowing LS1/LS2/LS6 style cylinder heads has outstanding potential for N/A and forced induction applications at a budget–minded cost. Aggressive, bold, race–bred styling will make bad intentions clear for drag race, muscle car, marine, off–road, sandrails, pulling trucks, track, street–rod applications and more!

• The base is designed to be modular in configuration to accept a wide range of carbureted and EFI tops and to be attractive to builders and fabricators as the foundation for custom induction systems.

• Runner length and the tapered cross–section designed to perform well for a wide range of engine configurations

• EFI fuel rails are machined for –8AN O–ring Fittings with passages large enough to accommodate high fuel flows and dampen pressure pulsations in the fuel system and come standard with EFI Hi–Ram kits.

• Cast aluminum construction.

• Intended for use on N/A or forced induction engines in the 6.0 to 7.0+ liter range, max power at 7000–8000+RPM.

Holley EFI Mid-Rise Intake with 1 x 92mm GM LS Throttle Body Flange– Longitudinal Mount Plenum Top – For LS1/LS2/LS6 Cathedral Port

$983.95

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 10.44”, 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.

Holley EFI LS main harnesses have a map sensor connecter designed for use with an LS1/2 style map sensor. The 558-416 is an adapter harness that can be used to adapt any LS harness that uses a LS1/2 MAP sensor connection to a LS3 MAP, which is recommended for this manifold.

Provides great performance to 6500 rpm for street/strip performance applications while providing the look of a racing EFI intake manifold
Unique modular design allows the combination of a traditional dual-plane layout with an EFI manifold plenum to produce great mid-range torque without compromising top end power
Great for supercharged or turbocharged engines
Power band from 1500-6500 rpm
May require an aftermarket hood for some vehicle applications.
Cast aluminum construction
Intended for use on all GM LS Gen III or IV engines equipped with LS1/LS2/LS6 style cathedral port cylinder heads (recalibration of the ECU may be required when using this intake manifold design with OE ECU).
