123ignition has been active in the field of classic cars for more than 15 years and through this became a respected brand. The company started in 1992 and from 2001 fully focused on electronic ignition systems. The first prototype ignition was born out of passion a couple of years before. A project was started to provide an electronic ignition for a Citroen 2CV. This turned out to be such a great success that the project was turned into a product. Meanwhile, the assortment expanded more and more, and we can now offer a suitable product for many classic cars.
