Never seen anything so overly complicated in my life. In my last 3 cars I've never had this much trouble. Remove the ENTIRE glove compartment for a filter? You've got to be kidding me. Still, I did it because even after all that work it is still not worth paying the dealer to do it....but I came close.
To save frustration though you might want to do this every 20k unless you live in a dusty area.
