Review on ECOGARD XC35834C Premium Cabin Air Filter with Activated Carbon for Mercedes-Benz Sprinter 2500 DIESEL (2010-2020) and Sprinter 3500 DIESEL (2010-2020) - Optimized for Superior Performance in Car Air Filtration by Richard Rob

The product was the same size as the factory filter but did not have the plastic top and bottom (see my picture) as shown on the Revain website (see their pictures). The airflow arrow seems to be upside down from the factory MB filter (see my picture) if you pay attention to the orientation of the side flaps. Installing in line with the flow arrow on the replacement filter will not provide a good seal. The instructions that came with it say the filter is for a 07-08 Dodge Sprinter, while the Revain website lists many other models including my model year. No time for a return - I had to redo it to resize. The box it came in had the same part number as advertised on Revain. The filter material itself looks like a factory filter. Very confusing all around.
