Please note the following about the 123/GB
We strongly advise you to check the dimensions of the 123/GB with the original distributor.
The 123/GB-4-R-V-pos is a 123ignition that has vacuum advance. If you don't need this, you can contact us to order a 123/GB-4-R-pos (WITHOUT vacuum advance). As this 'special' is not often used, we don't have it in stock and you can only get it at special request. The 123/GB-4-R-pos costs €20,- less than the 123/GB-4-R-V-pos.
Please read the installation manual carefully. It contains more information about static timing and the advance-curves (often found on the last page), the specifications of the 123ignition and a step-by-step description of the installation procedure.
Coils 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 overheat again in the future. We recommend the 123 Blue Coil.
Perhaps you'll also need new spark plugs? At 123ignitionshop we have added the spark plugs most commonly used in addition to the 123ignitions we offer. See: the spark plugs list.

123ignition een geweldig aanrader
De 123ignition had ik jaren geleden moeten monteren. Wat een enorm verschil met de oude ontsteking. Regelmatige stationaire loop en veel beter trekkracht. Ik heb deze verdeler in mijn Austin Healey Sprite van 1966 met 1275 cc motor gemonteerd.
Goede service en snelle levering.
Helemaal super toen bleek dat ik het artikel niet nodig had en het terug kon sturen.
Waarvoor nogmaals mijn dank!
