took away 1 star due to getting the X kit and not the Z. The filter is the same and works fine, the difference is the X kit includes a metal washer for the oil drain plug and the Z kit includes a new plastic drain plug so depends on your model. I have a 2015 4 series and the filter is great and works great, been using them for 5 years but I also buy packs of the oil drain plugs since they never come included
