Did mine today after acquiring a long screwdriver to reach screws #5-7. This thread was a huge help as was this YouTube video that I found that I don't think has been linked here. It is for a G37, but very, very similar.
The first time I tried putting the assembly back in none of the 5-7 holes lined up. I re-tried it and they looked good. However, #5 didn't screw in flush, but it was solid, so I left it as is. Screw #6 was lost in the abyss when I tried to put it back in. I hope to find it and have better luck next time I change the filter.
This change will certainly give your back a workout!
Props to all the previous posters itt!
