This is the genuine BMW tool and I can confirm that it does fit and work ok on engine oil filter housing for my N43 and N20 engines. However, it is a slightly loose fit and so after use it twists and sticks to the plastic filter housing and needs to be twisted the opposite direction a bit to release. For the occasional oil changes, I'm happy to live with it, but if I were using it daily it would be very irritating.

Does not fit the filter cap for my N54 Z4, it's too small. If it fitted, the quality would be OK.
