123/Mercedes: Immediately improve the performance of your oldtimer Mercedes with 123ignition


How does the 123ignition work for your classic Mercedes 4- or 6-cylinder engine?

Discover how the 123ignition distributor works for your classic Mercedes 4 or 6-cylinder engine. By replacing all the mechanical parts (such as contact points, centrifugal weights, springs, bearings, and vacuum membrane) with just a single, rotating component (the central shaft with rotor), you get a maximum strong spark at every speed. The intelligent electronics in the 123ignition provide the correct timing advance and optimal ignition angle at different speeds.


The components responsible for setting the 123ignition timing are not subject to wear and tear and do not need to be replaced or readjusted after the initial adjustment. You can easily choose the correct ignition curve for your engine with a small switch behind the bolt in the housing. The timing advance curves are pre-programmed in the "switch" version of the 123ignition.
