123 Electronic Ignition (ID421)

123 Electronic Ignition System
This unique electronic ignition system features a fully digital advance mechanism and 16 selectable curves, making it suitable for all 1300-2000 4-cylinder engines up to 1981, except early Giuliettas with positive ground electrical systems.

For POSITIVE GROUND vehicles see our part number ID421P.

The unit is simple to install with only 2 wires to connect, and timing is also easily accomplished via a built-in LED indicator light. Once installed you can easily select between available curves.

Includes stock curves that simulate the original distributor in many European and US Market Alfas, as well as several performance curves suitable for tuned engines.

For replacement parts see our part number IC845 cap and IR982 rotor.
