Atomic LS Throttle Body
MSD's LS Throttle Body answers the need for a high quality throttle body with a mechanical throttle mechanism that bolts to most factory and aftermarket intakes. The parabolic bore form design helps deliver excellent drivability characteristics during part throttle that typical billet straight bore throttles just can't deliver. We incorporated factory style bearings and seals on the throttle that can withstand years of use on the street or strip.
Features:
- Parabolic design for precise control, smoother off-idle response and improved part-throttle driveability
- Contoured inlet profile outflows the competition's big-bore throttle bodies
- Less shaft twist for superior TPS signal stability
- Billet body with stainless steel shaft
- Robust throttle cam assembly, featuring a three-plate design
- Dual ball-bearing design offers shaft stability and smoother operation
- 4-bolt mounting for easy installation
Atomic LS Late Truck Master Kit (Gen IV 2007-13)
The GM LS-based engine has been embraced by hot rodders, muscle car fans and racers alike. The lightweight and compact engine produces plenty of power and fits easily in many engine compartments. However, trying to retrofit the factory EFI system into a street rod or muscle car creates a number of challenges from wiring to programming. Intimidating electronics and bulky wiring harnesses can quickly clutter the engine compartment and hurt the aesthetics of any hot rod. The massive factory ECU is not only a hassle to mount, but the sheer amount of wiring that goes along with it is simply overwhelming. MSD's Atomic LS EFI systems are designed to eliminate the intimidation and clutter when installing aftermarket EFI on an LS engine.
By integrating the ECU onto the fuel rails MSD has eliminated the bulky ECU and tangled mess of a wiring harness. The self-tuning technology of the Atomic system allows the average do-it-yourself hot rodder to easily wrap up an LS engine transplant. Initial setup is a breeze with the supplied handheld monitor and by simply answering a few car guy questions during the initial setup, your Atomic LS'd project will be ready to drive.

- Integrated Fuel Rails and ECU
- Wiredless technology reduces wire
- Self-Tuning
- No Laptop
