The 123\CITROEN-4-R-IE (also known as 123\DS-IE-R) is designed to replace the original Bosch ZV11/7 A 3 A distributor, that was used by Citroen in conjunction with the Bosch D-Jetronic injection-system.

The 123\CITROEN-4-R-IE comes in a Bosch-like housing, with a Bosch cap and rotor. Two extra outputs will provide the right signals to the injection-computer.

The unit is factory-set to provide the right advance-curve, for the DS21-ie and the DS23-ie.
