Description

The 123ignition system represents a remarkable advance in ignition performance for four- and six-cylinder Mercedes-Benz models from the fifties through the seventies. More than a distributor, the 123ignition is an elegant synthesis of new and time-tested technology, driven by a sophisticated microprocessor with onboard nonvolatile memory and a bank of preset digital advance curves that permanently eliminate the need for springs and weights.

The 123ignition combines precise, cylinder-by-cylinder power mapping, digitally stored advance curves and an optional digital vacuum advance sensor in a self contained design that minimizes moving parts and is virtually maintenance-free. Originally envisioned to bring classic cars into compliance with tightening European emissions standards, the 123ignition has been widely praised by the motoring press and adopted by enthusiasts as simply the finest electronic ignition system available for classic Mercedes-Benz automobiles.

Adapted for Secure Installation

Ours is the only 123ignition sold with the proper modifications to install in the 190SL engine without risk. The stock 123ignition is manufactured in a generic Bosch-style distributor body which cannot be securely fastened in the 190SL distributor bracket without modification.

This version of the 123ignition supports the following 4-cylinder Mercedes models without vacuum advance/retard, including stock 190SL:
