Please note the following about the 123/Mercedes-6-R-V-OLD
For more recent 6 cylinder engines please order a 'normal' 123/MERCEDES-6-R-V.
For 6 cylinder electronic driven fuel injected engines (when the engine needs a trigger pulse form the ignition), please order the 123/MERCEDES-6-R-V-IE.
Please read the installation manual carefully. It contains more information about 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 future. We recommend the 123 Red Coil.
Perhaps you will also need new spark plugs? At 123ignitionshop we recently added the spark plugs most commonly used in combination with the 123ignitions we offer. See: the spark plugs list.

Excellent product and service
Één en al lof
Nadat de originele Bosch ontsteking van de Mercedes Ponton 220S stond te ratelen en te tikken, toch besloten voor een nieuw(er) stukje techniek te gaan; de ontstekingsmodule van 123ignition.
Het uiteindelijke resultaat van het functioneren van deze ontsteking is verbluffend en bijzonder eenvoudig te installeren met de beknopte handleiding.
De Ponton loopt als nooit tevoren, wat het rijden van de auto absoluut heeft verbeterd.
Mijn dank is groot voor dit geweldig stukje techniek.
