BTW, replacing the boot on an X3 is by no means simple or straightforward. It was much harder than a 330. Took me probably 4 hrs start to finish.
You've got to dismantle the plastic firewall bits, remove the DISA and a few other joys that I have purged from my memory. Everything is real tight up under the intake manifold and none of the hose clamps are in a position that you can get to without cursing and contorting.
I do pretty much all of the work on my own cars, but if I were doing it again, I'm not sure I wouldn't farm it out to an indy shop.
