I installed mine this past weekend. The install went smoothly. The only slow part was removing the strange hose connections on the OEM tube.
Also, I found it easier to remove the 45° elbow on the intake tube and then install the u-bend hose instead of installing it while in place.
I cut the tab on the plastic engine cover. It's so far back there that no one will ever see it, and it really does make a huge difference as far as room goes.
Here are some pics:
