Elbe Engineering EFI conversion kit (EFI)

Never-Installed EFI Conversion for Mercedes-Benz M116/M117 K/KE Jetronic Engines

Offered as a never-installed, fully complete Elbe Engineering EFI conversion kit, this system is designed specifically for Mercedes-Benz M116 and M117 V8 engines originally equipped with Bosch K-Jetronic (CIS) or Bosch KE-Jetronic (CIS-E) fuel-injection systems. The kit arrives with its original manufacturer’s box and includes every component required for a fully reversible installation.

This EFI system replaces the traditional distributor with a modern electronic ignition setup and integrates an included ECU for precise control. Benefits include improved ignition performance, increased fuel efficiency, smoother operation, and more accurate fuel metering. Bluetooth connectivity allows data monitoring via Android devices, simplifying tuning and diagnostics. No irreversible modifications are necessary, preserving the option to return to the factory system.

The seller reports that the kit is complete, unused, and located in Charlotte, North Carolina.
