Please note about the 123/Porsche-4-R 123ignition
Please read the installation manual carefully. It contains the specifications of the 123-ignition system, as well as a step-by-step description of the installation procedure. The installation instructions also contain a cross-reference between the original Bosch number and the setting of the 123/Porsche-4-R, as well as a list which links engine numbers to the required setting of the 123ignition.
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'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: the spark plugs list.

Fantastic replacement for the original distributor on my Porsche 356c 1965
Easy to fit, timed perfectly first time. Works amazing.
123 for Porsche 356B T5
Excellent product. Replacing the original distributor and doing away with the consdenser has really sorted out the ignition issues I have had on my 356. Very much recommend this.

Ware kam promt, ließ sich leicht einbauen.
Etwas mehr Beschreibung zu dem einen Programm, was letzlich nur für den 356 möglich ist, hätte geholfen.
Läuft im Einsatz aber gut!
