The Atomic EFI outshines the competition in ease of installation and performance! The MSD annular ring injection design produces an air/fuel charge with much better mixture as well as an even distribution among the cylinders that our competition cannot match. Better AFRs equal better idle quality, better starting, and better overall drivability throughout the rpm range. You and your engine will be glad when you Go Atomic.

  • Throttle Body Assembly (An exact swap for a 4150 Holley)
  • (4) port style injectors
  • EMS (Engine Management System)
  • Comprehensive Instruction Manual
