Sometimes when I buy oil filters from the dealer they are hengst, other times Mann. The one in front of me now says KNECHT. Made buy kirloskar KNECHT filters India. It came in the new authorized and Genuine MB parts box with the sealed hologram. The names you have listed are familiar to many people on this forum and they are what you will get from your dealer.
