When you're serious about power for your LS or new LT1 engine, call in the AirForce! MSD Atomic AirForce intake manifolds have been designed using Computational Fluid Dynamic Modeling to create optimal plenum volume and efficient paths for improved airflow and distribution to stock and modified engines. Their unique bell-mouthed runner entrances maximize airflow and minimize shrouding--efficiently using the available plenum volume for an unobstructed flow path over opposing runners. The 2-piece molded polymer design resists heat soak, minimizes weight, and allows easy access to the runners for porting. MSD Atomic AirForce intake manifolds accept an OEM or 103mm throttle body, as well as stock, aftermarket, or Atomic LS EFI fuel rails. They are supplied with new gaskets and hardware for a direct bolt-on package. The 103mm throttle bore allows the use of large throttle bodies for greater airflow, and a direct-flow path runner design promotes maximum airflow.

These MSD Atomic EFI fuel injection systems are the perfect choice for anyone planning on converting from carburetor to fuel injection. They include a throttle body, power module (with wideband oxygen sensor), and handheld controller. The throttle body features an integral ECU built on the side, incorporating the TPS, MAP, IAT, and fuel pressure sensors, all in one location. Fuel delivery is provided by four precision 80 psi injectors featuring a stainless steel ball and seat metering method for maximum internal sealing. They also use internal fuel rails, providing a sleek appearance and removing fitting connections where leaks can develop. Atop the Atomic EFIs are annular booster rings that deliver superior atomization of the best fuel mixture, ensuring the best possible fuel delivery. Best of all, the MSD Atomic EFI fuel injection systems bolt directly to any standard square bore carbureted intake manifold and accept the same linkage as most carburetors. The 1.75 in. diameter throttle inlets ride in precision roller bearings for a smooth pedal transition. The Atomic EFIs' unique TPS is a self-calibrating, non-contact sensor, which means that you don't have to worry about configuring it during setup. The included power module is a remote mounted piece that handles all of the high-current loads. MSD's CAN-Bus technology allows for a single, clean connection between these units and the throttle body mounted ECU. Control all of the MSD Atomic EFI fuel injection systems' functions with the hand-held device. Initial setup takes about five minutes, and you'll answer six questions about your specific engine. After the initial setup is complete, the device can provide you with engine data to help you keep your engine working properly. They also feature a removable micro-SD card to record and store data so that you can see what's going on with your engine.

Multi-port EFI systems require a stable fuel supply to maintain the best performance throughout the engine's rpm range. MSD high-pressure, high-flow fuel pumps feature a roller vane pump mechanism, which is extremely resistant to clogging and jamming. The pumps mount in-line (out of the tank) with two supplied cushioned clamps for a quick and sturdy installation. The wire terminals feature brass studs for secure connections. These MSD pumps are ideal as "boosters" for nitrous oxide applications, or as stand-alone pumps for multi-port EFI systems on engines up to approximately 500 hp.

Communication is important. MSD Atomic EFI TBI handheld monitors are the devices you use to interface with your Atomic throttle body fuel injection (TBI) system. You'll be in the know about everything happening with your engine, from exact air/fuel ratio readouts to engine coolant temperatures. Not a software engineer? You don't have to be! True to MSD form, these handheld monitors are very easy to use. In the initial setup, you'll provide info that you already know--such as cubic inches, number of cylinders, and your desired rev limit. After that, you simply use the engine feedback as you would a dashboard gauge. Plus, the data gathered doesn't just disappear. The monitors display alerts and save them for up to 10 starts for you to review. Little device, big communication--MSD Atomic EFI TBI handheld monitors keep an eye on your engine's performance.

MSD replacement oxygen sensors serve the fundamental purpose of providing accurate exhaust gas information to an engine control unit (ECU) or a data logger. For typical vehicle applications, this information allows the ECU to optimize the air-fuel mixture for maximum fuel efficiency and reduced emissions. For performance and racing applications, the MSD Wide-Band O2 sensor modules provide detailed air-fuel ratio data to the MSD Power Grid, which helps in custom fuel calibration and recording.

If you're upgrading the intake manifold on your LS engine, then you'll also want one of these MSD Atomic throttle bodies. They feature a parabolic design for precise control, smoother off-idle response, and improved part-throttle drivability. The throttle bodies are manufactured from billet aluminum, with a stainless steel shaft and contoured inlet profile—which outflows the competition's big bore throttle bodies. A robust throttle cam assembly uses a 3-plate design for smooth operation, while the dual ball bearing shaft offers less shaft twist and better signal stability.

The GM LS Series engines are being built for a lot of different performance and racing applications. You can see good ol' hot rodder ingenuity taking place as racers are running carburetors and even using distributors on these engines! These MSD LSx trigger converters plug into the factory crank sensor of an LS engine. They then convert the factory trigger signal into a 12 V square wave signal to trigger an MSD ignition control such as a 6 or 7 Series ignition control. If you are incorporating a front mount distributor into your LS engine, this means that you won't need to run an external crank trigger.
