123/MERCEDES-4-R-V-IE, with trigger impulse

123/MERCEDES-4-R-V-IE distributor for Mercedes with 4 cylinder engines with fuel injection

The 123/MERCEDES-4-R-V-IE is just like the 123/MERCEDES-4-R-V designed for the W110, W115 and W123 engines, but WITH a Bosch D-jetronic injection system (a D-jetronic has 2 extra contact points for controlling the injection).

Features of the 123/Mercedes-4-R-V-IE electronic ignition

Next to the standard-curves, the unit offers optimized advance-curves for driving on LPG or E85, the new Bio-Ethanol-fuel of the future. The unit has a built-in LED for easy static timing and several different advance-curves.
It also offers:
- Vacuum advance
- Automatic dwell
- Automatic power-cut after 1 second
- Gear shift retard

Please note the following about the 123/Mercedes-4-R-V-IE

Please read the installation manual carefully. It contains more information about motor- and distributor numbers, static timing and the advance-curves, the specifications of the 123ignition and a step-by-step description of the installation procedure.

Coil and spark plugs

Although used coils all look alike, they should be viewed with suspicion since one cannot tell from the outside whether, and how often they were exposed to overheating in the past. Installing the 123ignition system will ensure that the coil will never be overheated again in the future. We recommend the 123 Blue Coil.

Perhaps you'll also need new spark plugs? At 123ignitionshop we recently added the spark plugs most commonly used in combination with the 123ignitions we offer. See our spark plug page.
