The oil filter adapter on certain BMW vehicles often leaks oil when its plastic housing warps from harsh underhood conditions. As the plastic eventually degrades from heat and chemical exposure, it can even crack from simply tightening the oil filter cap during oil changes. When it fails, replacing it with an OEM housing could mean the same issues again in the future. This upgraded Dorman OE FIX filter housing is made entirely of aluminum for a more durable replacement of the failure-prone OEM housing to help prevent future leaks. The housing comes complete with mounting gaskets for an effective repair. The kit also includes the oil cooler, oil filter element, and oil filter cap.
