Thanks !! That is why I like to ask before buying. I always learn something new. You guys are AWESOME !!!It is literally printed right on the air cleaner lid. Mann+Hummel, the folks who made the whole air cleaner. If your car has no snow screen, you use the cold weather filter (that's what the "/1" at the end of the Mann part number means).
Hengst or Mahle are fine, too, but I try and stick with who made the filter assembly for replacement elements.
