The SilverLine system is based on the technology of the VSI system.
The main difference relative to the VSI system is that special Prins injectors have been developed for the SilverLine system. In addition, the SilverLine system is only suitable for 3 or 4 cylinder engines with a maximum power output of roughly 180 hp. The VSI system, on the other hand, is suitable for engines with up to 16 cylinders and a power output of as much as 900 hp.
The SilverLine system is an alternative to the VSI system, and only available in a limited number of countries.
