Atomic EFI Throttle Body Master Kit

Install Saturday Morning, Make the Cruise Saturday Night with the Atomic Master kit. The Atomic EFI outshines the competition in ease of installation and performance!

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.

This is the complete kit for anyone planning to convert from a carburetor to Atomic EFI. You get the Throttle Body, Power Module (with Wide Band O2 sensor), Handheld Controller, and the Standard Fuel Kit for up to 525hp (at the crank).

  • Bolts to standard 4 barrel intake manifold
  • 8 wire connection installation
  • Replaces standard square bore carburetor
  • Controls ignition timing
  • Integrated ECU and sensors
  • Single fuel line
  • Self-Tuning
