BMW X7 Hidden Rear Air Filter - 3 Minute DIY

[@danielbjohnson]

While you made a video for front and rear can you review a video how to apply cleaner spray. The air intake which is normally on the windshield is really hidden on the car. Bmw dealer charges 140 dollars to spray microbe disenfectant spray into the intake and I'm not sure how to accomplish the same task.

Is the filter quality good? It is made in China. Does it have any standards?

Most filters are pretty much the same and are made in the same factory. Of course, you can just buy the BMW filter if you are concerned.
