I'm talking about the inlets, underneath your stock airbox inlets are located. Do you even know what
i'm talking about? You'll see them if you take off the grill you can see them. They have little one way doors. They only swing in the direction to let air in, and not out. My post prior, was what My theory was on what are they needed for. Why would you have these tiny *** little trap doors in an air inlet tube. Well for some reason, they don't want what ever it is that goes threw there.......to get out.
That's why I'm talking about the colder climate stuff. The most sales for Mercedes isn't the US. we sure do like them here, but I don't see us using them as Taxi Cabs like in some parts of the world.
