Everyone who drives this vehicle also knows the problem with the relatively small air filters for the intake air of the engine. As with this engine the very large air intakes of each insect and what always flies around directly swallows, the filters are relatively fast on long motorway rides. When I saw this week in a workshop an S class with the CDI 320 engine, I was amazed. In the S class the intake air opening is covered by a plastic part on both sides. I would have liked to show you a photo, but did not find one at a time. I would try to screw a metal part from the inside on the upper radiator lamellas. Or to attach to the Schossbrücke bell plates. Ultimately, the insects etc. should not be able to fly directly into the air filter box. Has anyone tried this before? What do you think of this idea?
