I got one about a month ago that didn't come with one. The next day I called to get the boot and they have completely redesigned the setup. There is no longer a plastic boot, it goes to a rubber elbow. Now for the good part...the only way to get this elbow is to get the entire hard line from it to the IAC. It is formed slightly different and comes with protective foam around it to keep it from rubbing on all the other crap around it.
