I used Hengst cartridge oil filter in E430 several OCI, it worked very well and filter media after 12-13k miles still in perfect condition, it could be used for another 12-13k miles OCI, I changed it out because I have more than 7-8 filters for that car in the stash. The other German made cartridge oil filters for German engines such as Mann, Bosch, Mahle ... are very good too.
