10 min operation. Pop hood, remove shroud over top of engine that has the bmw Logo on it (held on by hidden clips, it just pops off). You will see the two air ducts from the front grill area leading to the air box at the back near firewall. Remove the clips (there are some at the back as well). pop off cover and you will see the filters. remove and replace. put back together in opposite order. that is it. Good luck.
