Product images may differ from actual product appearance.

MSD Atomic Electronic Fuel Injection (EFI) LS Master Kits meet your LS EFI needs by containing everything needed to complete your LS swap (fuel pump, hoses and injectors not included). This new, innovative technology simplifies LS engine swaps. Each kit is designed for a specific engine and includes integrated fuel rails, brackets, hardware, power module, handheld monitor, WBO2 sensor kit, crossover fuel line, injector retainers and harnesses.

Installation Kits complement the LS2/LS3 Master Kit by providing necessary brackets & injector connectors to complete LS1/LS6 or LS Truck Kit installation.

Features
  • Easy Setup
  • No Laptop
  • Self Tuning
  • Integrated fuel rail and ECU significantly reduce the amount of wire
  • Improves the aesthetics of the engine bay with less wires and NO ECU to mount
  • Compatible with return or return-less fuel systems
  • Automatically recognizes 24 or 58 crank trigger wheels
  • Kits available for LS1/LS6, LS2/LS3, and LS7

    Note: LS2/LS3/LS7 and Early Model LS Truck Kits are not legal for sale or use on pollution-controlled vehicles.
