Air flow speed can have a lot to do with the filters effectiveness. Also the design of the filter and housing-ductwork also has to control water from entering the engine.

The syncro also have the swirl type dust separator before the filter. This works very well in high dust/dirt environments. For normal use this set up is easily a 50K mile solution.
